Armored Core

"Congratulations [troper], from this point on, you are a Raven."

The Armored Core series is a mech-combat video game series developed by From Software. It started on the original PlayStation, and over the years, has been on the PS2, PSP, PS3, Xbox 360, and mobile phones. With the exception of Armored Core 2, each numbered sequel seems to take place in a different continuity, separate from previous, and later, numbered titles.

The games in the series and their plots are:

Armored Core - In the distant future, the majority of Earth's population has been wiped out in an event known as the 'Great Destruction.' In the wake of destruction, humanity has been forced to live underground, and corrupt corporations battle for supremacy. You play as a 'Raven,' a mercenary of the Ravens' Nest group, who pilots an Armored Core (AC), the eponymous Humongous Mecha.
 * Armored Core: Project Phantasma - A Raven operating out of Isaac City receives a mysterious request, to 'infiltrate the Amber Crown.' No corporation or sender name is given, and due to the amount listed in the monetary reward, the danger is obviously great.
 * Armored Core:Master Of Arena - In one of the corporation's more violent battles, several innocents are killed in the crossfire. One man loses his entire family, and a few months later, he decides to take revenge on the pilot responsible, the Raven known as Hustler One, pilot of the AC named Nineball.

Armored Core 2 - Sixty-seven years after the first game, Earth's second largest corporation, Zio Matrix, attains the plans for a research project on Mars, dating back before the Great Destruction. They launch the terraforming project, which causes the Martian atmosphere to approximate Earth's. The other corporations learn of the project, and follow Zio Matrix to Mars, bringing the battle between them from Earth to Mars. As a Raven, a mercenary of the group Nerves Concord (similar to the Ravens' Nest of old), you don't care about any of that. It's all about the money.
 *  Armored Core 2: Another Age - Five years after Armored Core 2, the corporations have all fallen in favor with the Earth government after the incidents on Mars. The people, still living in subterranean cities are tiring of being ignored and armed revolts are a daily occurrence.

Armored Core 3 - Set in a post-apocalyptic future, society lives in a subterranean society known as Layered. It is ruled by an AI construct known only as the Controller, which dictates nearly everything that goes on in the world. The major corporations Mirage and Crest, and the smaller Kisaragi vie for dominance. The Controller's strange actions seem to indicate that it is going haywire. You play a Raven of the game's mercenary group, this time known as 'Global Cortex'
 * Armored Core 3 Portable
 * Armored Core: Silent Line - Following the destruction of the machine-run society of Layered, mankind seems to be back on it's feet, and has begun repopulating above-ground cities. All seems to be well, and reconnaissance teams are sent out frequently, to determine what has changed. One area, however, seems to be unable to be scouted, and is dubbed the 'Silent Line,' as all communications past that point go silent. As a Raven of Global Cortex, you're employed to find out what is behind all this.
 * Armored Core: Silent Line Portable
 * Armored Core: Nexus - Years have passed since the incident at Silent Line, but as always, the corporations are still at war with each other. Navis, a new corporation, is obviously much smaller than it's competitors, but has complete control over a new resource. As a Raven of Raven's Ark, you are employed by various corporations to deal with this.
 * Armored Core: Nine Breaker- During a rare lull in the war between corporations, humanity is finally in a state of relative peace. All the world is happy for this change, save one organization. This organization does not want the world to return to the state of constant war, but does not want the Ravens, who will man the front lines in the event of a future emergency, to become complacent. The goals of this organization are- to hone the skills of the best, and provide a sufficient, capable fighting force should the need arise again in the future. Often thought of as the worst game in the series.
 * Armored Core: Formula Front - As the newly hired architect for a new team in the Formula Front league, your job is to design and assemble the team's ACs.
 * Armored Core: Last Raven - In the wake of Navis' attempt to recover and use lost technology, the world has been left in ruins. The major corporations have merged into one super-corporation known as 'The Alliance.' Fed up with corporate rule and oppression, one Raven known as Jack-O forms an organization of his fellow Ravens known as Vertex, out of the ashes of the Raven's Ark. After collecting a sizable force, he declares he will announce an all-out war with The Alliance in 24 hours. Leading the opposing force, a Raven known as Evangel has created an equally large force to combat him. You are approached by both forces and will ultimately be the one to take down The Alliance, or uphold the corporate rule.
 * Armored Core: Last Raven Portable

Armored Core 4 - The human population experienced an exponential increase, putting a strain on global food supply. As populations increased, so did the gap between the rich and the poor. The governments of the world began to lose control of their populations, and the six major corporations stepped in, declaring an all-out war. Using advanced AC technology known as NEXT that relies on Kojima Armor, they toppled the world's governments in less than a month, and worked out a new system of government, Pax Economica. Under this system, loyalty to the corporations provides one with food and shelter, essentially forcing people to be slaves. The Ravens have essentially been destroyed, and most pilots are either forced to patrol the colonies for meager pay, or side with one of the armed rebellion groups.
 * Armored Core: For Answer - After the events of Armored Core 4, the desolation and destruction of the surface via pollution of both Kojima particles and production has forced many portions of humanity, but especially the rich and powerful, to live in aerial Cradles to avoid the pollution of the surface. The NEXT pilots, known as Lynx and organized by Collared, feared and renowned for their skills, have been left on the polluted surface to rot and fight in the perpetual wars. However, not everyone's going to stand for this for long.

Armored Core V - After long, bloody war has polluted most of the Earth, humanity is sequestered in a portion of land that has grown into a large Megapolis simply called The City. Led by a despotic ruler called "Father", The City manages to get by even during harshest of conflicts, except when the local La Résistance takes matters into their own hands and initiates a coup. The prologue story opens with the bitter defeat of the Resistance, but later, they rose up again, emboldened by the addition of a very skilled AC pilot: you. However, things get more complicated with the introduction of a nefarious third party called The Corporation, seemingly aiding the rule of Father by supplying them with strange, often powerful technology, while at the same time, pursuing the Player Character relentlessly.

Armored Core V is an online team-based multiplayer game in the same vein to Chrome Hounds. Furthermore, the eponymous Armored Cores seem to have been scaled down to a "mere" 5 meters tall, as well as making it grittier and real...er, making them very reminiscent to Front Mission wanzers. The story for the single-player campaign mode is told through 9 lengthy Story Missions. After the conclusion of the main storyline however, the player character, and the two Mission Control character banded together to become freelance mercenaries Walking the Earth, narrated through simpler bite-sized Order Missions, amounting to an astounding 83 of them. Here too however, it follows a less-detailed B-plot detailing one of the main character's origins, the Mercenary organization Men of Honor, and a band of 13 powerful AC pilots called the Zodiac. New to the series is the ability (at a cost) to essentially repair, rearm, and remodify your AC in the middle of any Story Missions on pre-set places. Also different is the big change in controls; ACs capable of raw, astounding speed are no longer the norm. Instead, the terrain plays a very important role as ACs can now walljump quickly from places to places, and most maps feature very detailed and varying terrain unlike its predecessor. The new mechs even feature a function to essentially kick any targets, dealing damage according to speed and weight of the AC. The online gameplay has been described as "mech game meets Tower Defense", in which most online interaction between teams of player are measured in territorial assaults and controls, most of them involving invading a map guarded by turrets. If the invasion is intercepted however, the game switches into Team Deathmatch mode that pits a maximum of 5v5 players, 4 as Ravens, one as Mission Control complete with its own battle overview map. In addition, special events include Extra Missions that pit a maximum of four players against a variety of gigantic Bosses, some of which had a variant within Story Missions.

"Hustler One/Nine Ball/: Target Verified. Commencing Hostilities."
 * Ace Pilot - Every AC pilot is one, so Raven's and Lynx are judged by how many other Aces they can kill.
 * Affectionate Parody - AC's very own Parodius is called Metal Wolf Chaos.
 * After the End - The post-Great Destruction world. The world of the Armored Core 3 universe had just recovered from its own Great Destruction-esque event, and then Armored Core: Nexus goes and blows it all up again, leaving you to sift through the rubble a second time in Last Raven. Armored Core 5's world.
 * A.I. Is a Crapshoot - Surprisingly for a mecha series, usually averted. Most of the featured A Is are designed to kill people, and that's what they do. Played straight more than a few times though.
 * All There in the Manual - Given some Blind Idiot Translation and No Export for You for some of the extra material collections and artbooks, you need to do some digging to understand some of the games plot.
 * Thankfully, The Wiki Rule has helped to alleviate this some.
 * Almighty Janitor - Armored Core 3. Go ahead, try to challenge Exile without adequate preparations because he's in the bottom rank, I dare you.
 * AC2 has its own Almighty Janitor in the form of Matthias.
 * Played straight with Werehound in AC2. His profile basically states that he could climb a lot higher, but stays in rank 43 on purpose to stop newbs from advancing further.
 * SAMSARA also takes on this role at rank 22. His description says he enjoys crushing dreams of aspiring pilots.
 * Amazon Brigade: Interior Union, all of their hired pilots are all female. Even their mission broker is a woman.
 * Case in point, only Sir Maurescu from AC4 is male; all Leonemeccanica and Melies (which merges into Interior Union) Lynxes put together are all females: Sera Angelic, Ay-Pool, Stiletto, Wynne D. Fanchon, and Kasumi Sumika
 * Arm Cannon- There are quite a few arm models that are just guns attached to the Core, from laser rifles to bazookas to machine guns.
 * Armored Coffins: No Ejection Seat exists within the AC in any incarnations until Armored Core V (Where you bail out with a jetpack on your back). To prevents ravens from abandoning the mech in hopes of surrender.
 * Art Major Physics - Realistically, whole Quick Boost system in 4 and For Answer would put the pilot and machine under incredible stresses due to the massive G forces involved in speeding up and slowing down.
 * A Taste of Power - The AC you pilot in the Tutorial Mission of 5 when you first create your character is well-stocked and uses Second Generation parts all around. Then the tutorial ends and you end up with Junk parts in your Garage.
 * A-Team Firing - Arms Forts seem to have trouble hitting anything; in "Defeat Arms Fort Cabracan," an allied Giga Base Arms Fort in visual range can't land consecutive hits on the immobilised Cabracan, a vehicle the size of a city block and as tall as an aircraft carrier stood on end.
 * That's because it's shooting at the massive swarm of attack drones, not the Cabracan.
 * Another Century's Episode -
 * Anyone Can Die  in 5
 * Authority Equals Asskicking - In For Answer, two of the CEOs of the megacorporations are also high-ranking Lynxes. You can even hire one of them (Takafumi Arisawa) to be your wingman; apparently he doesn't mind putting his life in constant danger in exchange for being a walking advertisement for his company's products. Japanese fans have nicknamed the enormous cannon mounted on his AC the "CEO Cannon".
 * Awesome but Impractical - Several weapons in the series are like this, until they were replaced with Kojima Weapons in Armored Core 4.
 * Parrying blades, or physical blades, are arguably like this. They feature a long wind-up sequence, has cripplingly short range, and are finite in uses. Despite their potential one-hit kill attack powers, they are outweighed by their disadvantages. The for Answer version and the ACV version, Heat Piles, avert this.
 * Arms Forts are remarked in-game to be the ultimate projection of military strength. You get to blow one regularly.
 * The Torus Assault Cannon against anyone with an actual brain.
 * Some of ACV's Overed/Ultimate Weapon falls into this. The most famous example, Grind Blade, is a large, six-bladed, rotating superheated chainsaws. It does what it is advertised: killing other ACs in one hit, but it has a crippling feature that other models don't have. The Grind Blade ejects the entire left arm for the energy input to connect to the Core, thereby forcefully purging the left arm weapon as well as the shoulder weapon if the arm features a left-handed shoulder weapon, making a use of this particularly tricky, especially in light of the common Overed Weapon's Necessary Drawback of slow activation time, limited active time, charge time, and once-per battle usage.
 * Awesome Yet Practical: Grenade Launchers are this in 4/4A. It deals tremendous damage with a large explosion radius (so much so that the explosion radius had to be nerfed in 4A), and it does even more damage combined with Primal Armor-eating machineguns/gatling guns.
 * Arguably Sniper Cannons. Slightly gimmicky to equip (being very heavy and having less raw power than 'nades), sniper cannons' tremendous muzzle velocity means that if shot, it will hit 8/10 times at max range. Doubly so in matches with slightly laggy net. To make matters worse, for Answer changed the sound effect of sniper cannons so that it seems as if a silenced cannon. With no explosions to tell that you're being shot at, you can spend upwards to a minute to realize you're being sniped and by then, you'd probably have lost a significant chunk of your AP.
 * Sniper weaponry is good and all, but nothing screams Awesome and Practical like 4/4A Railguns. To elaborate, sniper weaponry have tremendous recoil and only dedicated machines can handle it. Railguns have zero recoil and competing muzzle velocity in addition to awesome PA-penetration rating. Plus, unlike energy weapons, railguns are not affected by energy weapons-compatibility rating. Coupled with fairly high ammo count, railguns are easily one of the Game Breakers in PvP. Of course, They Changed It, Now It Sucks, in a very literal sense (it since has been rendered unplayable due to nerfs).
 * The Overed Weapons Mass Blade and Huge/Giga Missile has been known to be very usable even in Multiplayer. The Mass Blade is a monstrosity of an Improvised Weapon, being a collapsed concrete girder attached with rockets used as a mech-mounted gigantic hammer with bent iron bars as its "hammerhead". Not only it features the lowest drain of all OWs, it has a low energy charging requirements and can be fired off three times with the right setup, instead of the usual two for most models. The Huge Missile is, Exactly What It Says on the Tin, a very large, possibly nuclear-warheaded missile. Capable of one-hitting an AC caught directly in its blast, it is even more useful in multiplayer thanks to a weapon called the Target Gun, which enables the user and the user's teammates to lock on to a target even beyond an obstacle. Since the Huge Missile homes on targets and is vertically launched, thereby clearing any obstacles, many teams use it to its fullest advantage having a different, "reconnaissance" oriented teammate tag a target for it to fire, with documented videos showing it killing two players at once.
 * Badass Normal: You in the Nexus/Last Raven series, in a world dominated with every other Raven equipped with HUMAN PLUS and OP-I. You are the only raven without the upgrades.
 * Base on Wheels - The land-based Arms Forts are either crawlers or massive walkers that easily fit the trope; Spirit of Motherwill is basically a walking aircraft carrier.
 * Battleship Raid - Arms Fort missions from For Answer are long, drawn out, often spectacular fights with your Core taking on fortresses the size of cities, many of which have to be destroyed in sections. Well, other than "Defeat Arms Fort Stigro."
 * Actually, only the Spirit of Motherwill requires this in order to be defeated. The Stigro, Giga Base, Answerer, Land Crab, Sol Dios Land Crab, Jet, Eclipse, and Great Wall can be easily defeated with a single hit.
 * While Sol Dios Orbit can be ohko'd It still requires you to take out the cannons, and Great Wall can only be damaged from the inside.
 * Actually if you time it right, the sol dios crab will release the cannons, then you immediately 1 hit it with a laser sword, and they will die as well. Actually very easy to do.
 * BFG - Pretty much all the guns featured in the series.
 * To clarify, the opening cutscene to For Answer shows that a basic rifle has to be transported to the launch site by a helicopter, which is slightly smaller than the gun itself.
 * Deployable weapons, the Giga Cannon and Legion/Multiple Pulse Ultimate/Overed Weapon in 5 really get the point across by being much bigger the the AC itself.
 * Black and Gray Morality - In For Answer, you have to choose between
 * In Last Raven, you have to choose between helping
 * Black Box - Appears twice in Armored Core: Nexus, once when and happens again at the hands of
 * Blind Idiot Translation - Ok, so the ith / is confusion in Japanese is well-known after the Aeris / Aerith saga. "Megalith" is a word in English. "Megalis" is not. Guess what the giant power plant in the two AC4 games ended up called?
 * There's a fair bit of Engrish in the translations, but the briefing videos have even more Engrish, due to the fact that most of them are not edited. Case in point for the Megalis above, the video refers it as "Megaris". Good English, that.
 * For reasons beyond reason, but the original Japanese Play Station 3 version of Armored Core 4 correctly names the powerplant Megalith.
 * Also, know that weird-looking NEXT that shows up at the end of AC4 and acts like the pilot knows you? If the translation had been done right it would be clear that was actually . This information was helpfully totally removed from Sega's localisation, meaning you're challenged by an awesome-looking robot for no apparent reason who wants to kill you, also for no apparent reason.
 * Being armed with that knowledge upon going into For Answer would have also helped to explain why the was now piloting a insanely modified version of some barely-mentioned enemy AC he (as far as we Americans knew) had met all of once on the battlefield for no apparent reason.
 * Makes more sense in Hard Mode, in which you face off against White Glint several times, proving himself to be an incredibly difficult opponent at times. Usually because he's helping the NEXT you're trying to kill.
 * Nearly every mech in ACV is called an AC. Many suspect this to be Bamco's fault.
 * Blinded by the Light - 4/4A gives you 09-FLICKER Flash Rockets. These literally are flashbang in rocket form and having it set off anywhere near you means that you lose lock-on capability for some time. Very bad against close-range combatants like Anjou/Ange, and especially Shinkai. Getting hit by an Assault Armor in 4A will also produce this effect.
 * In ACV, Flash Rockets are universally hated for their large area of effect and cripplingly long effect. Latest patches have nerfed the weapons.
 * Bolivian Army Ending - Occurs at the end of  in which the suicide bombing robots emerge  en masse, released   to rain death on any and all targets of opportunity. Your pilot is tasked with defending one of these, and as your operator laments that "it may be too late", you start controlling your mech through the cutscene, and as bomber after bomber smashes into you and you get warnings that AP is dropping to less than 10%., the screen fades to black. This is also
 * Bonus Boss - Arena fights because if the game has an arena (excluding Master of Arena) your never required to finish it to finish the storyline and if you do more are usually added after you beat the game. In the more usual sense Armored Core 2: Another Age had the lost field missions.
 * ACV follows the footsteps of Chromehounds by introducing ACV's bonus bosses:
 * LLL: Fought in the Story Mission. It got a massive upgrade on health and now more relentless in its attack. A gigantic six-legged Spider Mech that is taller even than most Arms Forts. Its Weaksauce Weakness is its laser cannons that unfold from its legs. Due to the armor, it is actually Overed-Weapon proof.
 * Exusia: Also fought in the Story Mission. A humanoid mech not much larger than ACs. However, it has supreme maneuverability and has overwhelming firepower. Not only it is now colored red, it has a dramatically different attack where it will literally grow gigantic laser blades from its wings and zips around the stage trying to slash you from the sky.
 * Raijin: A gigantic bomber aircraft, downing the plane seems to be easy. The stage that follows however is a winding maze filled with lethal turrets, with the wreckage of Raijin itself being strong enough to deploy an Overed Weapon grade cannon.
 * St. Elmo: A true Battleship Raid if there is one. Rather, the stage contains two St. Elmos. A large, armored battleship containing more armament than Spirit of Motherwill. Up to and including a Huge/Giga Missile armament that, yes, can kill you in one hit if you're not careful.
 * Type D No. 5: A revival of the great Armored Core tradition of Gigantic MTs, Type D is nearly 10 times the height of a single AC, armed with two FINGER-like Bazooka hands, massive missile battery boxes, and a main cannon powerful enough to destroy an AC in one hit. It is also colored red. To make matters complicated, it is also capable of deploying very powerful boosters to change locations around the stage. Oh, and getting hit by the exhaust hurts you too.
 * Boring but Practical - Machine guns. Not counting the famed Chain Guns, a lot of players fall back to mostly machineguns to do a lot of their gruntwork for them (ie, dispatching anything short of a full-fledged AC/NEXT); sure, a laser rifle looks cool (and most likely lethal to boot), but machineguns have copious amounts of ammo, more likely to track even the fastest of enemies, and provide a steady stream of damage and can easily wipe out scores of MT/tank/helis/whathaveyou in no time. In 4A, (regulation 1.40, at least), if you can hit NEXTs with it, the humble machine gun can eat away the mighty Primal Armor of a NEXT like cookies, and equipping two of them kills light NEXTs in 20 seconds-ish of sustained fire.
 * The rifles seem to get a second lease of life in 4/4A. A dual rifle/assault rifle combination is very popular in player-versus-player matches; something that was unheard of in pre-4 games due to several factors: Not only opponent NEXTs have gotten much faster than machineguns can keep up with, Primal Armors made machineguns much less effective by themselves. Hence, the faster-firing and faster-velocity rifles/assault rifles is the new standard.
 * HEAT Rockets in ACV might be dumbfired, but the sheer attack power and the relative ease to equip (being relatively lightweight, with close to zero drain) made them valuable for that extra punch on something that is not moving for several seconds.
 * Bragging Rights Reward- In many of the games, getting 100% completion would give you the ability to use overweight mechs. That is, after beating every mission and finding every hidden part with one robot, you're allowed to make a new, extremely slow one with any weapons or parts you like.
 * We can do better than that. In 4A, getting 100% completion unlocks
 * Breakable Weapons - Implemented (poorly) in Silent Line, in which any weapon that hit you basically had a percentage chance of destroying weapons you were holding. Was revised in Last Raven, in which damage to specific body parts would accumulate over time and decrease the effectiveness of those parts until they could be repaired. If the damage was severe enough, the parts would have to be repurchased entirely.
 * This also happens in some of the games intro movies.
 * Bullfight Boss - Stigro.
 * Exusia, due to its extreme maneuverability can also devolve into this.
 * Call a Rabbit a Smeerp - One mission in AC4 has the player intercepting "self destruct drones" fired from a submarine. Drone aircraft that only carry one warhead and are used only once are more normally called "missiles". That being said, the drones are much smaller than missiles and are much more numerous, clouding the horizon with an eerie shade of red.
 * Capcom Sequel Stagnation There were three games before Armored Core 2 was released, one more before Armored Core 3, six more before Armored Core 4, and one more before Armored Core V. There's usually enough content, new parts, and a new mechanic or two to make them better than the average Mission Pack Sequel, though, thankfully. From Software apparently just didn't want to change numbers that often. Also, a new number in the title usually means the start of a new storyline. The sole exception is Armored Core: Formula Front, a Gaiden Game that's basically a Fighting Game built on the Armored Core 3-series game engine.
 * Carry a Big Stick - Despite it's name the Mass Blade in 5 is this.
 * Chainsaw Good - The Grind Blade in 5.
 * Chess Motifs: ORCA strategist Maltzel has a chess piece for his emblem and refers to his proteges Hari and Vaoh as Pawns.
 * Chicken Walker: A common enemy to meet when you start your mech-piloting carreer, they only take a rifle bullet to put in the scrap heap. Alternatively, you can choose to equip your mech with "chicken legs", which are most often suited for air combat.
 * Colony Drop - attempts this at the end of Armored Core 2,
 * As the Player in Armored Core For Answer, you can drop no less than 5 of these in rapid succession, whilst a cheerful Russian records the killcount in blocks of twenty million murdered civilians.
 * Comeback Mechanic - Ultimate/Overed Weapons in 5 are intended to be this given that can one shot an AC...then again some of them can wipe out the entire team if timed right.
 * Competitive Balance - General AC types are Midweight Bipeds, Lightweight Bipeds, Light Reverse Joints, Tank ACs, Heavyweight Bipeds, Snipers, Missileboats, Pure Bladers, Balanced Bladers, OverBoosting Jousters and a few more. All of these archetypes are available to the player, provided (s)he can access the needed parts, with each style requiring different skills and tactics to utilize properly. If one wishes it is possible to blend two or more styles together, though the results of the more ambitious blends (like sniper OB jousting) end to either be unremarkable or somewhat crappy.
 * In For Answer, there are PA Bombers.
 * As of regulation 1.40, PA Bombers have been nerfed and rendered unplayable.
 * Continuity Nod - The games occasionally mention Hustler One/Nine Ball, the final boss of the first game, and the antagonist of the third. In Armored Core 2, one pilot claims to be his descendant (dramatic irony for those who played the first and/or third game, as Hustler One is an AI), and another's emblem is a red beast destroying Nine Ball's. He also appears as a Bonus Boss or Final Boss in several other games.
 * Furthermore, a number of iconic weapons or AC parts have been carried over from one game to the next. Among them are the high-powered laser rifle "Karasawa" (a.k.a KRSW and Canopus), named after one of the game's designers, and the "Moonlight" Laser Blade, which is named after the Moonlight Sword from From Software's first-person RPG series King's Field (said weapon has appeared in some form or another in almost every single game From Software has ever made).
 * Continuity Cameo - In For Answer, You may choose to fight against him or support him.
 * Okay, the reason that
 * In Armored Core 2, Leos Klein is outright stated in game, and on the promotional site at the game's launch, to be the original "Ninebreaker", the  from Master Of Arena. He was part of the Mars research project, making him at least 90 years old.
 * Characters from the japanese only story Armored Brave New World appear in the portable 3 era games as bonus arena fights.
 * Continuity Reboot - Several. AC3, and then 4, and now V. So with the exception of Armored Core 2, the series gets a reboot with each new number.
 * Convection Smonvection - Notably, averted. In any mission near lava or other high temperature environments, being anywhere near it increases your AC's heat. Post-Nexus, your boosters also contribute to your AC's heat output. If you pair really powerful boosters with a weaksauce radiator, your AC will overheat begin to take damage until it cools down.
 * Kojima does this too in 4/4A.
 * Corporate Samurai: Genobee in Nexus, Evangel and the rest of Alliance Tactical Unit in Last Raven. By the time Armored Core 4 and For Answer roll around, the Corporations have entire stables of LYNX on their payroll.
 * Corrupt Corporate Executive - Though you never meet them face-to-face, many corporations and their representatives show signs of this. While fighting off opposing corporations is the norm, some corporations may draw civilians into the crossfire (one Kisaragi mission from Armored Core 3 requires you to blow up a civilian monorail and make it look like another corporation did it, Emeraude in 2 has you blow up a solar power plant in order to cause a black out that will make Zio Matrix look bad, and in 4, .) Others may wage war against themselves or their own subsidiaries in order to prove a point. Crest and the OAE both do this in Nexus, Zio Matrix's entire Mars Division goes rogue in Armored Core 2 and sides with the Frighteners, forcing the head office on Earth to step in and obliterate it, and GA America and GA Europe go at it in 4, resulting in GA Europe and AkvaVit merging into Torus in 4A.
 * Cosmetic Award - You usually get the emblems from any enemy you beat in an arena match.
 * Covers Always Lie: Nexus, Ninebreaker and For Answer, despite the prominence of the AC's Oracle, Nine Ball, and White Glint on the front covers and opening cutscenes for the three respective titles, the number of times these AC's appear in game, not to mention their pilot's impact and relevance to the plot, is almost non-existent.
 * The Spirit of Motherwill in 4A is likewise. Endings B and C don't even require you to fight the damn thing (though it's preferable to fighting the Cabracan).
 * The US cover of 4 shows 3 NEXT's battling in Gryphon, this can't happen in single or multiplayer sadly.
 * Crapsack World: Taken to sadistic heights in Armored Core 4, you pilot a Core that uses a particle that kills the environment as you work for corporations who will gladly throw many lives away and in the sequel, It Got Worse.
 * Curb Stomp Battle - Poor AF Stigro's mission takes longer to load up than it does to destroy the target. The target is a colossal missile-launching hydrofoil with a giant bow-mounted sword blade. Know what else it has? No defence at all against laser blades. Sigh.
 * This is why you're supposed to equip the Torus Assault Cannon. Use that to fight him, it will be fun.
 * This troper was lured into a false sense of complacency due to the above statements when he first fought the Stigro. What the others haven't told you is that while yes, the Stigro has no defense against a laser blade, it's also nearly impossible to hit with a blade.
 * Also if you use rockets Stigro will go down in around four to five seconds FLAT.
 * Don't be fooled though. It is somewhat harder than it sounds to use a laser blade effectively on Stigro, and depending on which missions you've done, you may not have any kojima weapons. Still, Stigro is one of the easiest.
 * Overed Weapons are anti-AC weapons. They are, however, not strong enough to beat some of ACV's Bonus Boss in one hit.
 * The Phantasms from Project Phantasms mostly due the FINGER
 * Cutscene Power to the Max - Averted, though not apparent until later: Most ACs featured in openings (at least in earlier games) are overweight and impossible to make. That is, until you get Human PLUS upgrades. Other than that, most openings really depict realistic AC-to-AC combat like it would happen ingame.
 * In AC4/fA actually shows battles that would happen ingame realistically. Not only is it doable to do battle at those speeds, you can do it "faster".
 * Then again somethings you just can't do or just won't happen occur in the AC4/fA intros, like sliding down walls, or impaling your enemy with an assault rifle, or getting your weapon shot out of your hand. But hey Armored Core 5 added the sliding down walls part!
 * Cyberpunk Is Techno - At first. The series gradually goes from pure techno to synthesized orchestra. Played straight from Nexus to Last Raven, but by Armored Core 4, rock guitars are in full force for a Desert Punk vibe.
 * Cybernetics Eat Your Soul -  in Armored Core 5 lampshaded by
 * "I guess you did give everything up for the project, your body, your brain...your soul, am I right ?
 * Dark Messiah - You in For Answer if you choose Ending C.
 * Destroyable Items - In Last Raven parts of the AC's anatomy were damageable and would lead to noticeable drops in the AC's performance if they were destroyed. A busted head means no more radar. Lose an arm? Kiss your weapons good bye. Busted legs=crippled AC. And a destroyed core left your AC nothing but a fiery wreck.
 * Deus Exit Machina:
 * Disc One Final Boss:
 * Driven to Suicide - In Armored Core 5
 * Dub Name Change - Overed Weapons to Ultimate Weapons in 5
 * Oddly-Named Sequel 2: Electric Boogaloo - See the list above.
 * Elite Tweak - And then some. Each game boasts hundreds of different parts, each part boasts dozens of different stats, and dozens of parts go into building an AC, not including the time spent on the paint job and emblems. One can spend more than half the game constructing and tuning the AC for optimum performance.
 * Enemy Mine - Basically happens in every game, since all Ravens are mercenaries and will often be recruited by corporations that they may have fought in the past.
 * Even Evil Has Standards - For Answer's Ending C features
 * Ethereal Choir: 4A's entire soundtrack is riddled with this. Most noticeable in Today, White Glint's battle theme. 4 has it in the Overture and Mr. Adam, among other songs.
 * Exactly What It Says on the Tin - Last Raven's Pulverizers.
 * Executive Meddling - A minor variation: In Armored Core 4, several places that are named in missions (such as Old/Former Peace City) has had their locations changed between original Japanese Play Station 3 version and subsequent versions. At first, Former Peace City is located on what used to be Las Vegas (or at least somewhere in the State of Nevada). The US-version changes it to somewhere in the Middle East.
 * A more major version from the same game is that, thanks to Qurac-influenced Theme Naming in Eqbal's products, most of them were named after Islamic terms, such as Tawhid (Oneness of God) arm-shotgun, Injil (Bible) reverse-legged part and Zakat (Charity) machinegun, amongst others. These were changed into meaningless gibberish such as Zakajj in subsequent versions. See also I Have Many Names entry below.
 * Also in 4 the 03-AALIYAH mecha became ALIYA most likely due to the singer who died. The first A and the H was added back in For Answer.
 * Expy - Some noticeable examples include your operator in for Answer to Sumika Juutilainen from Project Phantasm and every continuity having a Nineball expy. Hell Nineball himself is a expy to Char and official art makes him look kinda like Quattro Bajeena
 * Fan Vid - There are quite a few.
 * Face Heel Turn - Strung in 2,  in for Answer and   in 5.
 * Featureless Protagonist - The player character is always one of these. They are also referred to exclusively as "Raven" in the PS2 games or just "you" in Armored Core 4.
 * Final Boss - In order of apearance: Nineball, Stinger in Final Phatasam, Nineball Seraph, Scarabaeus/Filial, The Controller, IBIS, Nineball/Prototype Pulverizer, Nineball, Jack-O/Zanida/Evangel/Final Pulvurizer,  00-ARETHA Thermidor/ /Shinkai/Wynne D/Roy Saaland/,  Exusia
 * Flash Step - Not entirely. In AC4/fA, your mech has a Quick Boost option. It's exactly what it says on the tin, accelerating you to nearly double your speed for almost a second, allowing you to dodge enemy firepower. It's possible to do this while using your Over Boost, and the speedometer tops out around 2500kph while doing so.
 * Pro Tip: Equip two energy blades to dash continually (at least until your energy bar runs out).
 * Aretha, the Final Boss in 4, pulls this one off much better. The Quick Boosters on that thing are insane, crossing a distance of what appears to be several dozen meters within an instant.
 * Frickin' Laser Beams - Lots. From laser rifles to back mounted cannons, to cores that shoot pods that shoot lasers.
 * Friendly Enemy - This happens quite a bit but the two most prominent cases are Evangel in Nexus / Last Raven and Antares in Another Age.
 * For Massive Damage - Several enemies can be incredibly difficult, but 4A takes the digital cake on this one with the Arms Fort Answerer and Spirit of Motherwill.
 * All of the Other Arms Forts can be one-shotted by blades. Except Soldios Orbit on Normal Mode. It's possible to fool Great Wall into separating all its carriages without flying through them, and the Cabracan itself only takes a single hit before it stops being the actual target.
 * If blades don't work, resort to Grenade Launchers, which are the trope, plus area damage. On a side note, using these to defeat AF Answerer, while flying just below the horizontal missile launchers, essentially makes this the 3rd easiest AF to kill. Just kind of have to manually target though.
 * Ultimate/Overed weapons in 5 can one shot mostly everything in the game outside of bonus bosses
 * Gaiden Game - Formula Front has no canonical ties to the 3-Last Raven story arc.
 * Game Over - Usually, failing a mission will only cost the price of repairs and ammunition, but failing certain story missions will give you a game over.
 * Gatling Good - Notably, the Arms Fort Great Wall is armed with Gatling guns the size of battleships.
 * All AC titles feature gatling guns.
 * 5 added autoguns which are so big that you can't move while using it without a tank body. The USG-23/H gatling gun models, with the added rapid fire increase mechanic from high precision arms, have such a high DPS that patches nerf it.
 * Giant Space Flea Out of Nowhere - FROM must love this trope, take out the enemy and near death? Here fight a AC/NEXT or two.
 * Glass Cannon - In 4 and 4A, your NEXT better be capable of hitting 900kph with quick boost or you are going to die. Fast. Even with an AP in the 6 digits, you're going to need to dodge a lot of dakka to make it last.
 * In general the standard lightweight AC/Next build.
 * Gun Porn - The new Overed Weapons in ACV all have an elaborate setup sequence in which parts fold and unfold into their ready forms.
 * Guide Dang It - Good luck trying to find and/or unlock the secret parts in the 1-3 era games and in 5 or the  in 5 without one.
 * Hey, It's That Voice! - Fiona Jarnefeldt is voiced by Maaya Sakamoto, who also voiced Sumika Juutilainen all the way back in Project Phantasma. In English, she's voiced by Kari Wahlgren, best known to gamers as Princess Ashe.
 * And Serene Haze is voiced by none other than Major Kusanagi. Really, that low-pitched voice should have been a giveaway.
 * And of course, way back before she became Nanoha, Yukari Tamura was the "Standard"-type Computer voice in the first Armored Core trilogy, as well as being the occasional operator voice for the dropship you are using.
 * Armored Core 5 is loaded with this with voice actors like Tara Strong, Grey DeLisle, Laura Bailey, Roger Craig Smith, Grant George, Troy Baker and Nolan North being a few.
 * Tsuyoshi 'Bang Shishigami' Koyama as Old King. Er... wut?
 * The voice actor for Nohara Hiroshi, Fujiwara Keiji voices the nigh-psychotic  villain Chief in the Japanese version.
 * High-Speed Missile Dodge - Depending on your build, you can either dodge every one or simply shoot them down. Or not give a rat's ass. in fact, it's possible to kill a Missile Boat build by just shooting at him while he fires his missiles, as they explode right next to him. Note that the AI is usually more capable of this.
 * To be fair, the missiles do a tiny bit of splash damage when they blow up, so if you shoot just one missile in a cluster of missiles, you'll take out more than one because of the chain reaction. This is why Missile Boats die horribly against a machine gun, because one bullet is all it takes when the 50 missiles you just shot are within inches of each other and your face.
 * This trope may be the reason most Missile Boats use vert-fire missiles instead of head-on or sideswipe missiles. Doesn't help much against enemies with good air time, but you can forget about shooting down the missiles if you can't stay off the ground.
 * VTF Missiles are meant to subvert this as they do proximity detonation, but a fast and agile enough AC can still dodge it.
 * Humongous Mecha - MTs, ACs, and in the later games, NEXTs and Normals. NEXT's are around 10 meters tall. 5's AC's are around 5 meters. Then there's massive MT's and Type D No. 5 which are bigger than you.
 * 100% Completion- After beating the games, it's possible to go back and select any mission you like. Getting 100% completion means doing every mission and finding every hidden part. In universe some Raven and LYNX have a 100% mission rating.
 * I Am Not Left-Handed / Restraining Bolt - In Armored Core 2, it was possible to do something known as 'Limiter Release,' which gave your mech infinite energy for about 30 seconds, followed by an extremely long recharge time.
 * Would that make it Trans-Am, then?
 * Ultimate/Overed Weapons in 5 are this by removing the limiter in the AC's generator to charge the weapon for a massive attack.
 * In a more traditional sense to I Am Not Left-Handed, it's a common play style to equip guns on a sword AC and then drop the guns after using up the ammo and switching to your comfort zone (swords)
 * I Have Many Names - Thanks to Executive Meddling concerning Eqbal's preferred Islamic-term-based Theme Naming, the SALAF, SALAUX, and the SOLUH refers to the same NEXT model.
 * I Love Nuclear Power - All over the place in the 4/for Answer games with Kojima technology.
 * Improbable Aiming Skills - The Spirit of Motherwill is able to snipe (at a distance of several kilometers) an extremely fast moving target with high caliber cannons with shocking ease.
 * Improvised Weapon - All of the Overed Weapons in ACV are not specifically meant to be used by an AC. Most weapons are held by crane-like arms, and in the case of Huge/Giga Cannon, crane arms with steel claws. But even then, the reigning king of improvised weapons everywhere is the Mass Blade: a heavy concrete girder with rockets attached to it meant to be used as a mech-wielded hammer with bent iron bars and spikes as its "hammerhead".
 * Incredibly Lame Pun - For Answer. Also, try saying the last three words in Armored Core 2: Another Age to see how that works out.
 * Armored Core: Master of Arena.
 * Instant Armor - Primal Armor in AC4/for Answer.
 * In Medias Res - The tutorial mission of ACV drops you into a burning city replete with (easy to kill, thankfully) enemies. Then it gives you some critical plot, in which you have no idea who is whom, and then a Boss Fight. This is then handwaved away as a dream you were having while going to execute a mission. Later on, you come across the exact same scenario, this time with all the clues that the game gave you beforehand.
 * Kill'Em All - Old King's solution to the question at hand in For Answer.
 * Law of Chromatic Superiority - Nineball, Amazigh and Hari but you can do the same things Amazigh and Hari can.
 * It's also perfectly valid for the player to invoke it as well.
 * In universe White Glint is this due to the name coming from how fast he moves so all you see is a "white glint". Also have a completely custom NEXT parts (until you get your own) helps as well.
 * Two bonus bosses of V are red even better, one of them is an upgraded version of the final boss.
 * Leitmotif - Nineball's 9, Spirit of Motherwill's theme of the same name.
 * Lethal Joke Weapon - Technocrat Company's FSS-53 Shock Rocket. Described in-game as "A dummy rocket that doesn't explode". The stats however says something else: it has the highest Primal Armor-reducing capability of any weapon, meaning one lucky hit and say goodbye to your usually very tough Force Field. To put things in perspective, weapons that usually do reduce PA does it by continuous hits, by large explosions, or the Awesome but Impractical Kojima weapons. This being a rocket shoulder weapon, not only you can spam it without needing to free a weapon slot, a good hit means that you can immediately follow up with weapons that deals most damage to PA-less targets. Like grenade launchers, for example.
 * Lightning Bruiser - Nineball.
 * Bigger case with Nineball Seraph, it's stronger any faster than anything you can build.
 * in 5 who is basically the fifth genrations Nineball even better
 * Any lightweight AC in ACV using a HEAT Pile can oneshot any AC. Except for tanks, which, even then, only require as much as a finger poke for it to die afterwards.
 * Lost Superweapon: There's usually one per game. Its relevance to the plot varies from game-to-game.
 * Lyrical Dissonance - Sort of. Nineball's theme "9" has a distorted, mechanical voice chanting to "Destroy Nineball." Which is exactly what the player is trying to do...
 * Machine Empathy - In AC4, the AMS Piloting System links the pilot to their AC for perfect reaction time. The title LYNX comes from the word sounding similar to LINKS.
 * Macross Missile Massacre - You can do this in all of the games, but 4A takes the cake. Starting with the Spirit of Motherwill, we work our way up to the Answerer. Barring Stigro and Orca's AFs, every AF has missiles by the dozen (Stigro has them too, but he's special).
 * One notable Raven in Nine Breaker has Missile's as it's weapon of choice (save for a Pulse Cannon ), the name of her AC, "MMM." Take a wild guess what that means.
 * Made of Explodium - Most MT s blow up after a couple hits from even the weakest of weapons and once you acquire the really heavy artillery stuff tends to explode if you look at it funny. AC s on the other hand are tough to bring down with even the best equipment. Anything larger (warship, building, Behemoth, Arms Fort) has a tendency to explode gigantically if you so much as poke it with a half-decent energy blade.
 * Mana Meter - ACs live and die by their energy bars. If an AC runs out of power it can't use its boosters or energy weapons until the generator recharges, which can take a couple minutes if you have an energy-dependant AC with a poor generator.
 * NEXT's are an even worse case; a NEXT that is not boosting is a NEXT that will die very, very fast.
 * Master Computer - R from Armored Core, The Controller from Armored Core 3 and IBIS from Silent Line,
 * and  in 5 in the same way Nineball might be.
 * Mechanical Evolution - The Pulverizers in Armored Core: last raven, as each one gets defeated a new one is made that's even faster and more powerful than the previous one, with tanks being the weakest and the strongest being a crazy airborne spidery looking thing that gives the alien queen a run for its money, the humanoid one interesting sits in the middle of the spectrum in regards to strength.
 * Mega Corp - Every continuity has one or several.
 * Memetic Badass - In-universe example; Nineball/Hustler One isn't actually the first/only one to hold the spot of #1 pilot, just the one that managed to hold it the longest. As a result, the title given to those that get to #1 are called "Ninebreakers." Nineball himself is practically a fan-based one, often being cited as the hardest boss in the series (e.g the Chuck Norris of AC's). Additionally, getting One Hundred Percent Completion in some games gives you a piece of him (e.g his head part, emblem, etc.)
 * Memetic Number - The 9th game in the series is Nine Breaker. This also shows in for Answer with White Glint being rank 9 and the mission you have to fight him in says that he's better than his rank suggests.
 * The final mission of Armored Core 5 is mission 09 and
 * Mini-Mecha - In 5 the AC are now 5 meters tall similar to Metal Wolf Chaos
 * Minovsky Physics - The Kojima Particles from Armored Core 4 are generated by a pseudo-radioactive substance, and are used to power the NEXT's forcefield-like Primal Armor as well as the Overboost, as well as several excessively powerful weapons. They are also highly corrosive and poisonous, turning anything powered by them into a Walking Wasteland. In some missions that take place in highly populated areas, you are restricted from using Primal Armor as a result, meaning that your Humongous Mecha is suddenly Made of Plasticine.
 * Mission Control - Most of the games have 'em, usually female.
 * In Armored Core 5, this is a player-handled role on team missions but is still done traditionally in story and free missions.
 * Mohs Scale of Science Fiction Hardness - Level 5, and even for a mecha series, Armored Core 1-3 is extremely hard only rivalled by Front Mission and Armored Troopers VOTOMS, your AC rarely have access to Easy Logistics (Out of ammo and don't have a laser blade? Too bad, you are officially hosed and must restart), Trying to play it like a Gundam Video Game will get you killed as energy recovery is not instaneous.
 * The Laser Blade and affiliated weapons (it would be a different story if all of them were labeled Pulse- and Particle-weapons) puts a dampener on practicality. Otherwise, this series offers a great insight of robotics: targets do not lock on immediately and depend on the processing power of the onboard computer FCS, Arm Cannon arms and rockets must be aimed manually compared to arms and missiles that adjust their aim based on the FCS, and (varying upon the game) heat is a major detractor to movement, and if you're not careful, could melt the circuitry (and possibly you) inside the AC.
 * ACV has gotten even harder on the scale, after they incorporated a lot of physics in the game. Case in point, Kinetic Energy weaponry (basically bullets) lose attack power and start to bounce off even moderate armor in long ranges. Chemical Energy (explosives) weapons don't lose attack power, but their trajectory is more parabolic and less accurate. Thermal Energy weapons (lasers, pulse) simply became ineffective due to diffusion with range. The best one? Charging attacks (that is, mech kick) is determined mostly by the leg's attack power, which corresponds to weight, and also velocity. Know what else uses those variables in real life? The equation to Kinetic Energy itself, one half times mass times velocity squared.
 * Moe Anthropomorphism - Since the series have next to nil human characters, most featured mechs have gotten this treatment in fanworks. Really.
 * Mook Maker - Arms Fort Cabracan.
 * Moral Dissonance - You do realise Exavil was an office building, right?
 * More Dakka - Ever-present in the form of Chain Guns, but applies doubly to any Arms Fort, which is essentially a mobile gun made out of other guns.
 * ACV one-ups the great tradition by offering Autocannons. Essentially as strong as regular cannons, with 3 to four barrels, and an extremely astounding fire rate. While all ACs require kneeling to use this, tanks don't, and in addition can dual wield it for even more dakka.
 * Multiple Endings - For Answer. Works a little oddly in that there's no clear decision point; it just comes down to seemingly arbitrary choices of the unconnected early missions what you'll end up doing, though there are a few obvious attack it / defend it mission pairs later on.
 * Last Raven also has this. The "canonically" accepted one is there one where . The other endings are just one of two variations:,.
 * Mythology Gag - Given all the different continuities there all over the place. Some examples are:
 * Your Operator in for Answer Kasumi Sumika plays a similar role that Sumika Juutilainen in Armored Core: Project Phantasm.
 * The way Wonderful Body moves in for Answer is in a simmlar way you pilot Armored Cores in pre Armored Core 4 games.
 * The Classic Pallets in 4/4A are color schemes from older games.
 * The ninth game is called Nine Breaker.
 * Michael. F in Last Raven Portable to Michael F from 4
 * The Moonlight due to it being in every game From Software makes.
 * Armored Core: Nexus and the Revolution disk.
 * Chief and Carol in 5 who
 * Neglectful Precursors - in Armored Core 2
 * New Game+- It's possible to upload your data from previous games in the series. In an interesting example, in the first and second games, getting 50,000 credits in debt resulted in your character being made "Human+ ," and starting over from the beginning with some bonuses, such as a better radar, double energy, and the ability to fire large weapons without kneeling.
 * Nice Job Breaking It, Hero - Happens quite a bit. Because he or she lacks a personality, your protagonist usually is usually quite slow on the draw and can be tricked into doing things detrimental to their own best interests.
 * Leos Klein lures you into a fight in the reactor room of a space elevator with the intent that the ensuing fight will cause massive damage one of Mars's most vital pieces of infrastructure.
 * However, the game warns you that collateral damage is possible before going into the mission, so if you're savvy enough you can put together a strategy that minimizes that collateral, such as luring Klein into close-combat with a blade, or simply using machine guns, snipers, and other single-target weapons in lieu of explosives.
 * Antares, who literally appears out of nowhere at the end of Another Age cons you into helping him gain access to Earth's version of the Mars space elevator, and then the government sends you in to clean up your own mess after he usurps control of said space elevator.
 * Not quite a con. Antares outright tells you he's keeping his objective a secret. As a Raven, your only interest in the end is money. Naturally, you don't care about either side. And since you get paid by both sides anyway, the situation is closer to Playing Both Sides.
 * The entire plot of Master of Arena is pretty much this.
 * In AC4, your ammo, repair, and operating costs all come out of your budget. Screw around too long and you can go into debt from a series of successful missions.
 * Same thing for online mercnary contracts in 5.
 * Nintendo Hard - Hard mode will kick your ass in 4 and 4A, Usually you complete your objective that isn't too hard, then a tough Next comes along, or 2! Or you have one target to kill, suddenly there is 4 of them, 4 crazy tough flying fortresses with mega damaging weapons. Or . Most Hard Mode's are not easy.
 * Occupation of Arteria Carpals, just Occupation of Arteria Carpals.
 * Not Quite Dead -  in Armored Core 5.
 * Ominous Latin Chanting - Around half of the songs in For Answer revolves around a pseudo version of this. Spilit of Motherwill (yes, Spilit), Today, 4 The Answer and Scorcher are standouts.
 * One-Man Army - Thermidor lampshades this in Ending C of For Answer, asking the player if he thinks of himself as a One Man Army. In actual gameplay this is mostly avoided.
 * In 5 you can be this given the games secondary plot line is the Corporation, Men of Honor and  trying to off you because your so dangerous.
 * One-Hit Kill - At least in 4 and for Answer, using dual energy blades on a four-legged chassis allows the blades to be thrust forward; dealing absurd amounts of damage that can kill anything if the enough of the animation connects.
 * Overed Weapons play this straight by do 60,000 to 150,000 damage a hit, the standard AC has around 34,000 AP.
 * Passing the Torch - Your character's operator (possibly mentor) in For Answer is.
 * Older Than They Think: Your part-time partner and proto-operator in Project Phantasma is also called Sumika. However, given PP and 4A take place it separate universes, it's not the same one.
 * Point Defenseless: Played straight, subverted, double subverted, averted, all over the spectrum. General rule of thumb is that any Close-In Weapons System designed to pick off incoming missiles mounted on your AC usually works, except when it doesn't (poor detection rates, etc). Conversely, non-AC opponent's CIWS will usually not work, except when it does (a particularly strong CIWS, for example).
 * One of the biggest recent aversion of this trope is the Aegis-CIWS unit onboard the St. Elmo. While it says it's a CIWS, it's more effective shooting down AC units rather than missiles thanks to its endlessly stunlocking bullets, not to mention St. Elmo is covered by six of them.
 * Pre-Ass-Kicking One-Liner
 * One of the biggest recent aversion of this trope is the Aegis-CIWS unit onboard the St. Elmo. While it says it's a CIWS, it's more effective shooting down AC units rather than missiles thanks to its endlessly stunlocking bullets, not to mention St. Elmo is covered by six of them.
 * Pre-Ass-Kicking One-Liner

": "Damage critical. Mission failed, #3/#8."
 * Preorder Bonus - Armored Core 5 had two, the Recon pack and Heavy Assault pack which gave some of the Overed Weapons early without needing to beat the game. Apparently Armored Core 4 had one which added two more NEXT's to fight in the Simulation (one of which was apparently Nineball) but it's most likely a Internet rumor since there's no proof anywhere.
 * Private Military Contractors: Raven's Nest, Nerves Concord, Global Cortex, Raven's Ark, Vertex, and Line Ark. They bill themselves as "Despite Resolution" firms, which is just a fancy name for "Mercenary Organization". Men of Honor in 5 does this in the more traditonal sense non story wise by having players hire other players to help them out in missions.
 * Psycho for Hire - Stinger, Shamir, Do Su, Chief most games has one.
 * Punch Clock Hero - See below.
 * Punch Clock Villain - Nearly every AC you fight against is one of these, as they are usually just recruited by corporations you happen to be fighting, corporations which may later recruit you because you killed their employees. Sometimes subject to Lampshade Hanging, including an instance in Armored Core 3 where Nocturne tells you "We're both Ravens, just do what comes naturally, and don't think about it." right before trying to kill you.
 * was also lamshaded in Armored Core 2, "We're both Ravens right? no hard feelings." the pilot's british accent makes it come off as kinda souless, making the line extra creepy.
 * Rank Inflation - Armored Core 3 through 5 so far rank mission performance thus: S, A, B, C, D, E. S is practically flawless, E in 3 to Last Raven and D in 4 to 5 is total failure.
 * Real Is Brown - Armored Core 4 has a graphics filter that will either make things: A. Brown B. Grey C. Too Bright D. Too Dark or E. Brown, said graphics filter was thankfully ditched in For Answer.
 * Subverted - Most of the Armored Cores themselves have bright, almost flamboyant color schemes.
 * Armored Core 5's stages are bleak and war ravashed using minor shades of brown and grey, the AC's are still as colorful as ever.
 * Real Robot - The MTs and Normals are about as real a robot as it gets, outside of Patlabour. The more powerful ACs and NEXTs develop immunity to g-forces, but are still fairly 'real'.
 * Rebellious Princess: Rosary aka: Cordelia
 * Revealing Coverup: Crest Industries' sloppy attempt to deny that The Controller is malfunctioning in Armored Core 3 only stand to confirm the Union's theory that it is malfunctioning.
 * Rogue Protagonist- White Glint in For Answer.
 * Running Gag - Meta version; every new game in the development will have the inevitable question "Is Nine Ball in it?"
 * Schematized Prop - Oh, god. Every part has exact and in-depth specifications for any attribute the part applies to, even the ones no one in their right mind would use.
 * Schiff One-Liner - Wynne D Fanchon from For Answer utters one to her defeated opponent in Ending A. As he sits in his destroyed mech, your opponent claims that your ideals will cause the downfall of humanity. Wynne replies: "Humanity? I don't see humanity anywhere, ."
 * Secret AI Moves- Aside from enemy ACs occasionally having parts that simply don't exist, the higher-ranked Arena opponents in 3 and Silent line have ALL the optional parts equipped, including the OP-Intensify (which, by itself) takes up all the slots on a Core).
 * Proudly presents : Rai-Den, god of QB-chaining.
 * Shoot the Dog - One interpretation of For Answer Ending C.
 * Shout-Out - Despite being 10 feet tall, Armored Cores have the the same feel as VOTOMS. They skid across the battlefield using a combination of boosters and feet, highly customizable, and some of the parts such as grenade launchers and missiles bear striking similarity to VOTOMS Ace Custom models. And don't get started on Kojima Particles...
 * There's one to the Xanth novels, of all things. In the first book there's a character that uses three pseudonyms: Then in this series there's the character
 * Every chapter in Armored Core 4 is named after a book by Agatha Christie.
 * Sibling Rivalry - Rosary and Regan
 * Skippable Boss - In some cases you are not obligated to kill certain boss enemies you meet and are encouraged to evade them to continue the mission uninterrupted. The bosses are usually hard enough in AC that some of them are considered Hopeless Boss Fights the first time you try them, but can usually be beaten after acquiring better parts.
 * Sliding Scale of Idealism Versus Cynicism: As a rule, Armored Core games tend to have a cynical worldview. A recurring theme is a decaying world torn apart by conflict while civilians are forced to eke out a living under oppressive Corporations. However, some games have been more idealistic than others.
 * The first trilogy of the game, Armored Core, Project Phantasma and Master of Arena is not as cynical, but does not elaborate on the worldview. At least, the first game ends on a zero sum game, while PP has you successfully destroy Doomsday Organization and Master of Arena culminates in, which has been manipulating events behind the scenes.
 * Both Armored Core 2 and Another Age were pretty upbeat, what with humanity successfully colonizing Mars. The threat of inter-Company conflict is present as ever, but 2 makes it pretty idealistic after defeating . Another Age is more ambiguous however.
 * The Armored Core 3 series is definitely the darkest. While 3 and Silent Line culminates with you freeing Humanity from The Controller's grasp and freeing the denizens of the other Layered, Nexus and Last Raven slides back into cynicism with unrestrained freedom that Corporations have and the world now marching again to the brink of ruin with no solutions present as the cruel leader of the La Résistance true goal is to prevent further destruction of humanity by destroying the source of said misery. It branches off with Ninebreaker/Formula Front in a what-if Navis was never formed and thus Nexus never happened. Ending the need of Ravens and turning AC combat into a bloodless arena battles.
 * Armored Core 4 and for Answer hits the farthest end of cynicism. Not only the world's government has been overran by the Companies, the new Kojima Energy brought untold pollution to the already resource-deprived world. In for Answer, the temporary solution was to evacuate Earth's citizens to upper atmosphere, and the only solutions to the problem are to maintain the ultimately destructive status quo, or to sacrifice millions of innocent civilians to open up space, the last, albeit uncertain hope for mankind or to commit a cruel mercy killing.
 * Armored Core V is set in an already scarred world with only pockets of civilization left. The Resistance aims to bring the despotic Father, ruler of the only Megapolis left in the world, down and to bring in a better reign. However, a group of enigmatic figures aid Father and actively hunt down the protagonist. After a massive debacle where no side won, the hard-earned stability of the City is gone forever, causing the land to become lawless, with roving Migrants and AC Pilots duking it out to become the best.
 * Smug Snake - Omer Science's briefing guy, especially during the briefing for "Destroy Arms Fort Spirit of Motherwill" where he spends quite a large amount of it making sarcastic comments about the Bernard and Felix Foundation and the Arms Fort itself.
 * Spell My Name with an "S" - "Zinovie" becoming Genobee, is likely a lost-in-translation error, as Zinovie is a legitimate Russian name. It was also possibly meant to be "Shinobi", but either way, Genobee'd still be wrong.
 * Malzel's name should have an umlaut, rendering it as Mälzel, which explains the pronunciation in the Japanese version.
 * SNK Boss: One could consider Nineball Seraph this since it uses parts you can't get.
 * Sphere of Destruction - Assault Armor in For Answer.
 * Spiritual Successor - Three of them: Chrome Hounds, Murakumo: Renegade Mech Pursuit, and Metal Wolf Chaos
 * Staying Alive - In Armored Core 5 has  who you knock into the ocean but comes back a few missions later which doesn't follow this trope until you fight him in a one on one duel and beat him there...but then he reactivates, reveals that he is an AI, rips a support beam out of the wall and tries to kill you with it. But it doesn't stop there, he comes back again as the final boss using Exusia. And it's implied in the ending that he isn't done there.
 * Super Prototype - Usually a few of them around in each game, whether its a mech or just a weapon part. Subverted in For Answer where the player's operator comments that because they are sending out last generation Super Prototypes ORCA must be getting desperate.
 * Tactical Rock-Paper-Scissors - Y'see, the best way to counter the missile spam is usually machine gun fire which is then best followed up with grenade lanchers or plasma weapons but this tends to not work well against skillful evasive maneuvers combined with a lightweight build. The best answer to the lightweight build tends to be missiles.
 * Tank Goodness - Even if the player doesn't use a tank type AC, at least a couple opponents certainly will.
 * Title Drop - Partial. In For Answer, Ending A, Kasumi Sumika/Serene Haze addresses the player, referring to their choices and decision to as the "Answer".
 * Happens in Ending B as well. In the final mission for that route, as you begin the mission, your operator says "You've chosen your answer. Now see it through."
 * Also in Ending A, should you be defeated and the final hit was made by Thermidor, he remarks to you "Sorry, but I won't let you take this from us. But I'll be sure to remember... your Answer." Lots of talk of the elusive Answer in the ending, huh?
 * Complete, albeit somewhat bordering on Incredibly Lame Pun: The gigantic flying fortress "Arms Fort Answerer"
 * The Dog Bites Back - In Armored Core 2, the once-weak Martian Government gets a sudden taste of power and promptly abuses the heck out of it. This leads to many Ravens (including their own hired guns the Frighteners) revolting to form a Raven's Republic when they are needed the most. For Answer had the ORCA Brigade, made up of dissatisfied LYNXs and most of all Old King.
 * Tomato Surprise - Somewhat rare in the fairly straightforward series, but the end of Silent Line reveals that The revelation is foreshadowed by
 * Also happens in Master of Arena:
 * Toxic Phlebotinum - Kojima Particles in 4/For Answer. They've been described as "radioactive" and "polluting" (the latter probably means "hard to get rid of"). A major part of the plot in For Answer is how humanity copes with the high levels of Kojima pollution due to the constant use of NEXT's.
 * Thanatos Gambit - The Union liaison in Armored Core 3 speculates that The Controller's "malfunctions" are actually an attempt to provoke humanity into defending itself and ultimately killing it. The people who worship The Controller as a god take it as a sign that it has decided humanity must die and gladly accept their fate.
 * That's No Moon - In Armored Core 2,
 * Theme Naming - Omnipresent throughout the series. What am I talking about? The pilots are referred to by either Lynx (in 4 and 4A) or Ravens (every game prior to 4) as a codename. They may have actual names, but a generic pilot is called either a Lynx or a Raven in every game.
 * Most part names in later games have this. For example in 4/4A, Leonemeccanica/Melies/Interior Union names their parts after stars and star constellations while Eqbal names their parts after Islamic terms (or Arabic-sounding gibberish, depending on the version). Algebra later settles with flower names.
 * On the other hand, Rayleonard Company's Berlioz and Supplice refers to composer Hector Berlioz and Marche Au Supplice (also a mission name), a part of his Symphonie Fantastique. This is of course, after we get past the fact that Rayleonard names their NEXT models after R&B stars: AALIYAH and ALICIA (Keys). A renamed generator part was actually named 06-RIHANNA.
 * Rosary's real name, Cordelia, her sister Regan, and Regan's bodyguard Oswald are all taken from Shakespeare's play King Lear. In a good bit of Fauxshadow, this does not lead up anywhere.
 * The Computer Is a Cheating Bastard -In your final fight against from Last Raven, her AC shows signs of damage. However, all this "damage" does is
 * In fact, most of the games are guilty of this, as many of the single player AC's you encounter have such idiot AI (such as attempting to boost through a 10 meter wide steel wall, conveniently relieving themselves of all their ammo, simply because you are on the other side of it) that FROM gives them all of the aforementioned superpowers. This is most noticeable in Last Raven, of course. Depending on the story path you take, you can end up facing TWO such opponents in the SECOND mission, WITH NO WARNING WHATSOEVER. Given Last Raven's attempt at more realistic mechanics, this did not go over well.
 * It's not just --virtually every enemy AC controlled by AI gets unlimited energy, superb aim when firing at your missiles from halfway across the map, and ignores fog.
 * Invoked with A Is: why doesn't Nineball need to crouch to fire his grenade launcher?
 * also does this too, using a fallen power line AS AN OVERED WEAPON.
 * The Poor Mans Substitute: A low-ranked Raven in the Arena in Armored Core 2 goes by the moniker "Hustler Two" (AC: Eight Ball). He claims to be a descendant of Hustler One, which is kinda hard to take seriously seeing as how . His AC is also hilariously shitty in comparison to Nine Ball.
 * The Revolution Will Not Be Civilized - Orca and Vertex, who is borderline darwinist in selecting rebels against the corporations
 * There Can Be Only One - One of the endings of Armored Core: Last Raven involves
 * Timed Mission: In AC4, you pay for your NEXT's operational costs, and you're charged according to mission time. While you don't fail outright if you take too long, you can easily burn more cash than you gain if you take too long. Some missions take longer to load than they do to beat if you're going for that coveted S-Rank.
 * Transforming Mecha: Nineball Seraph can legitimately transform into a plane mode. Something no other AC has replicated before, until...
 * White Glint in For Answer, though only if you don't use parts that conflict with its transformation.
 * White Glint's transformation is only seen in the intro movie and in the model kits--the only part of the transformation that happens in gameplay is the Overboost wings opening up.
 * Unstable Equilibrium: Nabeshima discussed this in an interview over 5. Specifically, he noted that most battles are "centered around how well you could dodge your opponent's attacks while firing away and gradually whittling down his AP...That's fun, of course, but once one side has an AP advantage over the other, it became difficult to come back from that. Overed Weapons are intended to dramatically change that battle balance."
 * Updated Rerelease: Armored Core 3, Silent Line and Last Raven (but no Nexus for some reason) were re-released for the PSP with the title Portable tacked onto the end. All three games featured brand new parts and arena fights not found in the PlayStation 2 versions of the games.
 * Useless Useful Spell: Assault Armor Does a nice little chunk of damage and can erase an opponents PA. however it also erases your PA even if you miss, it's range is quite short and it's utterly useless against Arms Forts and mobile fortresses. it is however, useful against blade build NEXTs.
 * And, by extension, any part that amplifies the damage done by Assault Armor.
 * Villain Protagonist: For Answer, Ending C.
 * Villainous Breakdown:  Poor   semi-psychotic voice bordering on insanity just makes you feel sorry for the bastard.
 * "This is some kind of a sick joke, right ? We turned ourselves into puppets for this?! I don't even remember why!"


 * Walking Wasteland - Any NEXT is this due to the ubiquitous use of Kojima Particles in their Primal Armor and possibly weapons.
 * Wall Jump - Added in 5
 * Wave Motion Gun - So many.
 * Weaksauce Weakness - The Spirit of Motherwill is beaten by destroying its weapons (because the explosions cause uncontrollable internal fires, a rather glaring engineering fault for a weapons platform), Stigro has absolutely no resistance to energy blades (which generally do a huge amount of damage when they land).
 * Arguably, BFF probably didn't think anything would be able to get close enough to Spirit of Motherwill to destroy its weapons in the first place, considering it can precisely hit a relatively small NEXT moving at least Mach 2 (You can hit as high as 2600kmph with the Vanguard Overed Boost.)
 * Well, they apparently don't consider a small one-man fighter to be any threat, or they'd have a tighter defense.
 * Pretty much any arms fort can be destroyed in one motion by any AC that has two energy blades and has a four-legged chassis.
 * Well-Intentioned Extremist- Line Ark is an aversion. While they were branded revolutionaries by the League, they're actually very democratic and accepts people from all walks of life. This approach however has led them into a massive Motive Decay. Line Ark's successor of sorts, ORCA in For Answer, is this.
 * We Will Spend Credits in the Future: Interestingly, only Stateside editions use "Credits". Japanese versions use COAM instead; short of COmpany Assured Money.
 * Credits are called "Au" in 5, implying gold is being directly traded but it still follows the trope.
 * What the Hell, Hero? - in For Answer can't help but register her disgust at the choices your pilot makes that lead to Ending C. The enemies who appear to kill you and your accomplice after the fated mission also lash out at you with the following, starting with your Operator herself:
 * "Please accept my apologies. That briefing you saw was manufactured. This is the end of road for you. I think you understand why."
 * "Your actions were clearly deliberate, there's no point in trying to reason with you."
 * "Maybe it's just an animal. Can it even understand what we're saying?"
 * "You think you're some kind of one man army? You think it's your right to choose who lives and dies?"
 * "You kill too many."
 * The icing on the cake is on the mission's Hard mode, in which  decides to try and back up those harsh words by also trying to kill you.
 * "To end up facing you like this... Too bad. You walked right into my trap. Stand still so I can cut you down." -
 * That mission has a Hard Mode?!?!!?
 * It's beatable...if you cheat.
 * And the worst part about it? Old King was the only true rebel leader against the corporations which speaks a about the rebel groups.
 * With This Herring - The Story Missions in V are often long, hard, and brutal. The beginning AC you have is nothing more than a hodgepodge of "Junk" parts; parts that are no longer in their peak state due to damages they've sustained, denoted with the prefix "D/".
 * Wolverine Publicity - Nine Ball is the series's unofficial mascot despite appearing in only four out of fourteen games. And any Armored Core fan worth their salt will recognize him.
 * It probably has to do that every Armored Core fan worth their salt has had their asses handed to them by it at least once.
 * Word Salad Title - Even in context some of the games titles are just weird. By way of example the thirteenth game's full is Armored Core 4: For Answer. Say that out loud and see how it sounds.

''Mission objective achieved. System switched to normal mode.''
