Kaizo Trap



"Oh...what?! ...WHAAAT?! WHAT?! ...What the fuck? What the fuck? What...the...fuck? What the... (bursts into tears)"

- Proton Jon encounters the Trope Namers for the first time in this Let's Play.

A specific type of Video Game Hope Spot. You've just single-handedly ventured through traps, Mooks, monsters and puzzles, unearthed the Big Bad's plan, and beaten the boss into a fine pulp. All is good, and now all that's left is to walk through the Level Goal and watch the victory cutscene.

Hang on, what's --

What? Did you just die? During the victory cutscene? And you have to do all of that again?

Yes, that's right, you just fell for a Kaizo Trap, a tremendously annoying case of The Computer Is a Cheating Bastard where a Death Trap is placed in a spot where you would normally have your guard down. Besides the end of a level, other examples can include a hidden Press X to Not Die during a Cutscene, and Press Start to Game Over, where you are killed before you can get your bearings. Intentional Schmuck Bait doesn't count -- you must be killed through inaction in a spot where you didn't even think you needed to be holding the controller.

Known in Japan as "Koumei no wana" ("Koumei's trap", "Koumei" being the Alternate Character Reading for Zhuge "Kongming" Liang, a famous strategician from Romance of the Three Kingdoms). Commonly found in Platform Hell titles, as just one more sadistic Screw You on the part of the designers. The opposite of this trope is Fission Mailed. Compare with Take a Moment To Catch Your Death, Yank the Dog's Chain and Diabolus Ex Machina... only for you, the player.

Action Adventure

 * In Bomberman 64, Orion, the midboss of Red Mountain, will vanish in a burst of flame when defeated. If you don't get out of the way (or have a heart item), you'll be killed instantly and forced to repeat the battle.
 * In Cave Story, the, one of the bosses , will fall through the floor after being defeated. If you're not alert and let it land on you, you'll die instantly, and you'll have to go through a difficult series of levels to get back to the same point again.
 * Several speedrunners like to use Mercy Invincibility from touching a Bute so that they can drop to the floor below at the same time as the .
 * Also, after the ghost Pooh Black is defeated, he can still give the player Collision Damage until he completely dissolves.
 * The Legend of Zelda Links Awakening has a rather infamous one. When you defeat the final boss' last form, before the boss explodes, the arms can still deal damage, even though its host is dead. This often results in death if Link does not have or used up the potion if you're low on health, because contact with the arms deal one full heart with no Mercy Invincibility.
 * If you are unlucky enough to still be in contact with the boss while it is giving its Final Speech, then it is literally a race between your hearts and the game's letter-writing.
 * An unintentional one in Batman Arkham City, where during the boss fight with  you can get run over by a train after you beat up all his cronies and, finally, the boss himself. And it will still give you the proper achievement even though you died.

Adventure Games

 * Douglas Adams' Starship Titanic had a bomb, whose artificial intelligence would keep losing count and restarting. If you failed to disarm it, then the Cutscene at the end would, although the game does still finish. It's really up to the player to decide whether or not they won.

Arcade Games

 * As mentioned in Credits Gag, the Tetris the Grand Master arcade games continue the game with invisible pieces during the credits. In the second game in the series, losing it doesn't matter unless you already have the second-highest rank (in which case surviving it will give the highest rank). In the third, just surviving it isn't enough; you have to play so well during the credits that the highest rank has only been attained by three people.

Choose Your Own Adventure

 * The Fighting Fantasy book Caverns of the Snow Witch has this: You've killed a yeti, defeated the titular Snow Witch, and escaped with 2 ex-slaves, . If you can't remember what the Healer's sign is at the end? Death.

Fighting Games & Beat 'Em Ups

 * The princess you're trying to rescue at the very end of Karateka will kill you and end the game instantly with no continues if you approach her while in the 'fighting stance'.
 * In Soul Calibur 3, Colossus will fall forward after you remove the last of its health. If it lands on you, you die and lose the battle.
 * See also: Zaugg, in Barbarian. Sometimes. (It seems to have been planned this way, but sometimes he goes straight through you as in a normal end-of-game cutscene elsewhere. Strange.)
 * White, the final boss of the Playstation version of Real Bout Fatal Fury Special will lie down and shoot a fireball from his cane when his lifebar is depleted: it needs to be blocked low or jumped over, and getting hit by it is an instant KO while the boss gets up and wins the round regardless.
 * After defeating Porky in Super Smash Bros Brawl, one of the legs will fall with enough force to hurt you.
 * Similarly, the Porky Bots don't vanish when he's defeated, hence you can get blown up by them after the boss has already been defeated if you're too close to him. Not too dangerous, since you can't get KOd if the boss is defeated, but devastating in Boss Battles when you don't want to take much damage or waste healing items.
 * Knocking a foe at an extremely high percentage upwards results blasting away so the animation goes on for a while before they actually die. In Sudden Death there's still plenty of time for a bomb to spawn on top of you and send you flying off this side killing you instantly while this is happening, so if you've knocked your foes up don't let your guard down.
 * The Ice Climbers can milk this in rare cases
 * The above "blasting away" animation can actually result in a Luck-Based Mission-style match result at times, depending on whether the animation for falling into the background or slamming against the screen plays. The slam kills you faster. Also applies if someone is on their last legs, trying to stay in the air as long as possible to avoid falling into a pit before their opponent twinkles/crashes.
 * Most bosses in the Splatterhouse series will throw you one last cheap shot after you've technically "defeated" them. some examples:
 * The hung corpse in the bore worm room has one last bore worm emerging a few seconds after the music calms down.
 * The poltergeist will attempt to drop a chandelier upon you.
 * The uterus thing in the Womb Level will explode, splashing you with (deadly) embryonic fluids.
 * Also, in the second game, the first boss' stomach explodes and kills you with digestive fluids if you're too close.
 * In Chiki Chiki Boys/Mega Twins for arcade and Maga Drive, there is a boss who will drop his pants after he is defeated. If the player character is hit by the pants, the player will lose control and then be forced to exit the stage without collecting the bonus money for clearing the stage.
 * If the game wasn't hard enough, Battletoads also has a kaizo trap of its own. After you kill the final boss and she falls through the floor, she will come back spinning in the middle of the room for a final cutscene. Get caught in the spinning attack and you're dead. Last life? Game over and you have to start the battle all over again. Oh, last continue too? You're back at the beginning of the game!
 * Posthumous double-K Os in Super Cosplay War Ultra are possible for characters with delayed attacks (such as Erus' coin special.)

First Person Shooters

 * On payload maps in Team Fortress 2, the attacking team's goal is to push a giant bomb-on-a-cart to your enemy's base, where it explodes. If your team succeeds, you can't just go blindly hunting disarmed enemy team members as on many other maps, without keeping well clear of the bomb.
 * On the other hand, a lot of players love to deliberately get themselves blown up or hurl themselves into the insta-kill pit that results, whether they win or lose.
 * A slightly more evil variety: enemy taunt-kills still can kill you during the post-match time. Even if said enemies lost the round and are thus in "Humiliation" mode, without their weapons.
 * There's also the Dead Ringer, an unlockable for the Spy that turns the next hit on the Spy into a fake kill, complete with death icon in the corner of the screen, point scores, Achievements, and everything else that goes with a kill. So while your opponent thinks they've killed you, you're getting away under a cloak...
 * In Perfect Dark Zero, after defeating Killian's gunship, it will try to kamikaze into you as a Last Ditch Move. This may just be a false alarm.
 * In the "Door To Chthon" level of Quake, you reach what appears to be the exit door, but the lights turn on to reveal a Shambler, with the true exit behind it.
 * Doom also did this - in the first game a secret level was an exact duplicate of the first map in the episode, until you stepped on the exit tile... and had the strongest enemy in the game appear from behind fake walls. The second game pulled a similar trick in the first map of Final Doom, but only had basic enemies in the pit you get lowered into when you try to exit the level. Doom II had a nasty section in the aptly named 'Tricks and Traps'' map - the final corridor to the exit lowers into an inescapable lava pool unless you know to run full pelt along it. The first time you play it, expect to reload.
 * Similar to the Wolfenstein 3D example below, the Hell Keep level had a false exit that dumped you into a pit full of enemies. Doom in general features a few occasions where the "exit" door hid an enemy or the switch inside opened the room to reveal an even larger than normal horde.
 * In Metal Gear Solid once the Ninja's life gets to zero, the boss music stops, but he's not quite defeated yet, and can still kill you with his force field.
 * As demonstrated by the target of this Retsupurae.
 * In Time Splitters Future Perfect, after a boss battle with Princess, some sort of several story-tall undead naked mole-rat-looking....thing, she/it will take one last swipe at you as she falls back in her pit. This is especially dickish considering one of the strategies for fighting her best is to stay close to the pit. Although if you do this, the last hit won't matter much whether it hits you or not.
 * In Timesplitters 2 the heli on the first stage can still vape you before you hit the portal if you both fire missiles at once, or worse, if it fires after you do. You see the explosion of yours, but not the trail of the missile it's covering...until its too late. (not to mention russian guards will still spawn until you actually step into the portal. Thankfully you are ALWAYS invulnerable upon entering/falling through a portal.)
 * Portal played with this at the end of Test Chamber 19. As you are being congratulated (rather sadistically), the platform you are standing on moves you to the "last" room, which turns out to be . Escaping from this trap gives you a rather satisfying result. (Historically, some players have thought the game ended with this trap. )
 * Wolfenstein 3D had a couple of levels with fake elevator doors that hid carnage (E1M10 comes most immediately to mind), and a lot of levels where the elevator itself housed an enemy or several (Oh god E4M8).
 * The first boss of the original Descent sometimes decides to fire an instant-death missile barrage right when you kill it. Also, all bosses explode when defeated, potentially taking you with them if you're low on shields. Keep in mind that every boss is a Load-Bearing Boss and the Self-Destruct Mechanism will start upon destroying them, so getting killed immediately afterwards results in your inventory being incinerated in the mine explosion. A few levels also have monster closets that activate after you blow the reactor.

Hack and Slashers

 * After defeating the Armadillo in Ninja Gaiden II, the camera zooms in so you can get a nice view of the thing dying... in an explosion big enough to kill you no matter where you are in the arena. The only way to survive is to abandon logic and block the explosion using that slender katana of yours (or whichever weapon you've been using).
 * Can also been seen in Ninja Gaiden: Dragon Sword. The final boss fight consists of stunning the boss over and over so you can hit him while he's down. When he has just a sliver of health, attacking him will stun him as it usually does... but approach this time, and he'll unleash an incredibly quick instant-kill attack which he's never used before.
 * In the first NES game, after defeating the Final Boss's first phase, its head flies off at you, and there's no way to avoid taking a hit.
 * In No More Heroes, Bad Girl- the 2nd-ranked assassin in the world- has one of those. After you get her down to fairly low health she may occasionally stumble and fall, then start crying. However, there is a very high chance that she's actually faking it, and going anywhere near her will result in an Instant Kill..
 * Likewise, when Shinobu is near defeat, she will employ her Instant Death Radius Desperation Attack. If she starts charging up, get away fast.

Interactive Movies

 * In the game Night Trap, it's possible to get a Game Over during the intro, with no clue that it's going to happen.
 * And to get it, simply by doing nothing. This was actaully quite common with a lot of Sega CD FMV games back then.
 * After beating the final boss of Braindead 13, there is one last action sequence while everything is blowing up before the final cutscene. Not only can the player die during this sequence, but no attempt is made to hide the cruelty: the player dies by a piano inexplicably falling on their head.
 * Dragons Lair 2 has two Kaizo Traps; one in Level 6 and one in the last level.
 * The first game, if set to Hard, also has a Kaizo Trap. As soon as Dirk kills the Bat King, if you think it's over, then the bats have a chance of making you lose a life.

MMORPGs

 * In World of Warcraft, after she's defeated, Vanessa VanCleef will activate one last set of explosives. In the original version, you had to swing off the boat like you did at 50% and 25% of her health, but in the current version, you have to run away from her.
 * Phantasy Star Online: When you've slain the Dragon at the end of the Forest area, as he dies, take care not to let the big fella fall on top of you.
 * Amusingly, the Ultimate-difficulty version of this is the most powerful attack in the game statwise.

Platformers

 * Named for the infamous Kaizo Mario World, a Super Mario World romhack, which is known for being extremely difficult, and for taking advantage of the fact that Mario can die during the victory strut after beating the stage, requiring the player to find out how to defuse the trap before walking through the end of the level.
 * See here for a Let's Play of one of the levels. It's both messed up and hilarious.
 * Here's the whole video on Google.
 * Kaizo actually subverts the trap in world 1-3, to surprise those who have heard of the trap before playing the hack.
 * Inverted in this hack, much to the amusement of the commentator. Even more amazingly, his decision to "humor" the creator of the hack led to him discovering the trick!
 * This could result in getting two extra lives, one for carrying the P switch to the goal whilebig Mario, and another if the player is close to one hundred coins.
 * There's an insane twist on the Kaizo Trap in the hack shown in this video, where you have to defuse the trap, then hope the blocks switch back to coins just before a certain point before you fall to your death.
 * That's called a Kaizo Combination Lock.
 * And here's Proton Jon's reaction to a Kaizo Combination Lock.
 * There are plenty of other Super Mario World hacks that make use of Kaizo traps, along with other creative uses of the engine, and unbelievably impressive 16-bit music to boot. Cool or Cruel (MAKJANG QUALITY) has a particularly cruel trap towards the end of level five.
 * In the original Super Mario World, after you defeated Big Boo, you had to land on solid ground before the victory would register. Some hacks use this to make the fight much harder by only giving the player 3 blocks, or just one throwable object that doesn't break (such as a key). This not only forces them to score a hit with every block while flying with the cape, but they also have to run into either wall in a way that would allow them to wall jump after the last hit, since there won't be any solid ground left, but the wall jump glitch works by making the game register as Mario being on solid ground for a split-second.
 * One of the levels in a Kaizo-style hack of Donkey Kong Country 2 uses such a trap to return you to the start of the level, when it looks like you've made it.
 * There are several Kaizo Traps in Rob Omb's Quest, an old Super Mario World hack starring a Bob-Omb. One level focuses on putting a bunch of goal spheres everywhere so that they're basically instant death. Another level, Castle Moat, has you go through an entire level and forces you to be small at the end. If you don't bring in a Spring Board from the beginning of the level (So it can turn you big so you don't fall into the lava), you fall in the pit of lava.
 * The secret level "Old Aquaria" in The Second Reality Project 2 contains one of these as part of the level's puzzle.
 * Super Mario Galaxy 2 has a glitch where you can die during the credits!
 * Also, Timed Missions in Super Mario Galaxy 2 stop the timer whenever a cutscene occurs in which the star appears (for example, upon collecting the 100th Purple Coin or defeating the boss). However, bosses often reel from the final hit for a second or so before the actual cutscene starts, so if you defeat a boss at the last second, that moment of "Phew, just barely made it!" can quickly turn into "Aw, crap!" Still, it's preferable to the first Super Mario Galaxy, where timers continued ticking until the moment you touched the star.
 * And while we are on Mario...In a romhack of Super Mario 64, called Kaizo Mario 64, the Kaizo Trap is inverted. You don't die in the ending cutscene, but during the level opening, unless you pushed the red cap switch. see here.
 * At the end of the final level of Super Mario Bros 3, because of the huge hole Bowser made in the floor after being defeated, it's actually possible to fall in it and die. This was fixed in the GBA remake, however.
 * At the end of the credits of I Wanna Be the Guy,
 * Fake credits roll in the middle of the final boss battle of Donkey Kong Country.
 * Donkey Kong Country 2: After K. Rool's final hit, he can still kill you with the very last cannonball.
 * Despite not generally being too difficult, Sonic the Hedgehog has this a few times.
 * In Sonic Adventure, Sonic's final boss enemy, the Egg Viper, once defeated, will fly around, on fire, for a while, and then crash into the stage, and instantly kill you by bringing you with it into a bottomless pit. Not only is this probably unsuspected for first time players, but if you spend too long defeating it earlier, it can actually destroy enough of the stage beforehand that there's no way to avoid dying later.
 * Some levels in the 16-bit Sonic games feature boss fights over bottomless pits, where the player can fall in and die, even after landing the final hit on the level boss. This includes Chemical Plant Zone from Sonic the Hedgehog 2, Angel Island Zone Act 2 in Sonic 3, and the final boss of Death Egg Zone in Sonic And Knuckles.
 * The Sonic & Knuckles final boss will actually kill you with your final hit if you attack from the rear and bounce back just as the screen stops scrolling forward.
 * Sonic the Hedgehog 4: The battle against the final Egg Mech he makes a last ditch effort to crush you. If you are too far from his landing zone the floor will collapse sending you to your doom.
 * Very nearly happens in Sonic Adventure 2 at Metal Harbour. Possibly on purpose by the designers. You're going so fast that when Sonic goes into the Goal Ring, he'll nearly fall off the edge, luckily, the screen fades to white for the results screen before this can happen.
 * Happens twice in Sonic the Hedgehog (2006). The Egg-Genesis will try to crash into you and The Egg-Wyvern will try to take you down with it. A glitch can actually let you be killed by the Egg-Genesis but still complete the boss.
 * In the first Mega Man game, you have to collect items that the bosses drop and projectiles don't disappear after defeat. That means that you can die right after defeating a boss and have to try again if you don't avoid that one last projectile. Which was problematic considering you couldn't move.
 * Mega Man and Bass does it too. While you are safe from projectiles after defeating a boss, a cage boss has a trap in store for you. After you defeat it, the platform you had to be on to damage him will fall into the acid. If you fall in, you instantly die despite it only doing some damage in the middle of the actual battle.
 * Speaking of Kaizo traps, this Youtube user decided to take advantage of a Mega Man 3 mechanic, where if you're not in the middle of a room when you defeat a boss, you fall right into a pit. You can find it here.
 * In Mega Man 10,
 * Made more annoying if you've beaten the game on Easy and are trying it on Normal. On Easy, Considering it can be That One Boss if you don't know the pattern, and on Easy just spamming weapons wins most of the time, chances are it'll crush you even more.
 * Once you win the second Boss Battle with Phantom in Mega Man Zero, he self-destructs to take you with him. Hope you weren't standing close. (Or had spare health, it's not an instant kill.)
 * Your Traintop Battle with Panther Flauclaws in the second game has you both leaping between trains to dodge attacks. Hope you weren't in the air between trains when you defeat him, as a glitch causes you to fall straight down when you do. (That is an instant kill.)
 * Also in the second game, you have to fight Herculious and Kuwagust Anchortus together. Once you deplete both their lifebars, don't get confident, because they'll try to catch you in one last pincer attack before exploding.
 * Better land on a platform after slicing Pegasolta Eclair in half. He still mocks you if you die, despite being completely in two. At least you can control your descent, and can actually keep him floating in air in his death post by repeatedly wall jumping.
 * Death from Castlevania tends to be one of these for the simple reason that, while most bosses' projectiles disappear when they bite the dust, Death's mini-sickles don't. It is possible to actually die from contact with one of them, so don't forget to take the Death Ring off...
 * Aria of Sorrow has no mini-scythes during phase two of the Death fight, but instead you have to dodge the gigantic double-bladed scythe that goes flying upon Death's defeat.
 * In the sequel, Dawn of Sorrow, certain attacks would continue even after you successfully sealed a boss. Death's skulls were by far the biggest offender, as trying to dodge a giant flying skull immediately after drawing a complex pattern on the touchscreen is easier said than done. There's a reason the Magic Seal is the Scrappy Mechanic of Dawn.
 * In Rondo of Blood, many bosses will get a final shot at you after their life bar is depleted; though this can't actually kill you (the exception being Shaft at the end of Stage 6, though this was fixed in the remake), they can reduce the level's "vitality bonus" to one and deny you the extra life you'd normally get for killing them without taking damage.
 * It was NOT. You can still die by being hit by the falling orbs just after you already beat Shaft, even in the remake. Although they fall so slowly it's just a matter of moving out of the way.
 * In Harmony of Despair, after defeating Beelzebub, there is usually one last swarm of flies coming to kill you.
 * In Order of Ecclesia, Death's other attacks continue when he dies if they are in use, not just the scythes. If you have the red skull swirl or the giant scythe attack at you, you better hope you don't have the aforementioned Death Ring equipped. Here it is in action.
 * In Super Castlevania IV, if you defeat Dracula with only a few seconds left on the timer, you will die before his extremely long death animation finishes and you have to fight him again.
 * At the end of Level 1 in Syobon Action, if you jump onto the flagpole normally, Level 2 also has a  Level 3 has  . In Level 4.
 * La-Mulana's Hell Temple, being what it is, has a nasty version of this. In the penultimate room, the entire left side of the room is fake; walking on it drops you into the Land of Hell a few rooms back.
 * In the Wii Ware remake
 * In Banjo Kazooie Nuts & Bolts, the deliberately awful mini-game "Hero Klungo Saves Teh World" has an attempted Kaizo Trap at the end of the last non-boss stage, where Klungo falls into a pit right after you pass the finish line. It's "attempted" because you still get credit for completing the level, but it since the whole mini-game is a parody of 8-bit Platform Hell, it was probably meant as a subtle Shout-Out to the original.
 * The fourth boss in Super Meat Boy qualifies if you try to dodge the boss's hands by bouncing off the really low placed walls (with special timing, of course). Do this long enough without dying, and the scene slowly fades to white, indicating that you beat the boss. If you're still floating above the lava during this sequence, however, you won't be able to hop back onto the platform, and then you'll fall to your death and possibly Rage Quit.
 * In The Bugs Bunny Birthday Blowout, there is one part where you can get killed by a football thrown by Taz after you defeat him if Taz throws one before he is defeated.
 * In earlier versions of Eversion, the Bonus Stage had one final hand just before the goal that would pop up if the current world was X-5 or higher. Later versions changed this so that the hand unexpectedly appeared close to the end even in bright and happy World X-1, but popped out too fast to actually kill the PC. Still quite a shocker for first-time players, however.

Puzzle Games

 * There are Marble Blast Gold custom-made levels where the finish pad is placed inside an "out of bounds" trigger. As a result, hitting it too slowly causes the game to reset just as you hit the finish.

Real Time Strategy

 * Red Alert 2 continued to check lose conditions after the win condition was met, even though the controls locked up and a banner covering half the screen saying Mission Complete popped up along with cheering sounds. Since the normal lose condition was losing all your units or the destruction of your entire base, the developers probably just didn't test the possibility, since the enemy would have to complete their mission in about 7 seconds after you finished yours. The problem was that there were Allied missions with a special agent who must not die, and while she was strong, she couldn't take on tanks. The cheering continues, but the lose banner suddenly appears over the win banner and the mission restarts...
 * The penultimate Soviet mission of RA1 combines this trope with blatant Railroading - your objective is stated to be "capture the chronosphere" but if you do so the mission fails. The actual win condition (which you are not told) is to destroy everything else except the chronosphere, after which you are treated to a cutscene of the device exploding anyway.
 * And Red Alert 3 continues the tradition in the Allied campaign with "A Monument to Madness". After completing the mission objective, a major target (that must remain alive up until this point) Chronoshifts from wherever it is to an airstrip on the southern end of the map between the two allied bases, where the target changes to a transport helicopter. If you didn't get that the enemy turrets were there for a reason and didn't station units there, well...

Rhythm Games

 * A bonus move during the end of Space Channel 5 is thrown into the end of the credits, often catching players off guard.
 * Along with that, anytime you face off against Purge. He'll usually have some trick up his sleeve.
 * The entire Bemani family of rhythm games love to put notes after the perceived ends of some of the more challenging songs.
 * Since the introduction of the Freeze Arrow in DDRMAX, many Dance Dance Revolution songs end with a Freeze Arrow, often on a jump on left and right. So In the Groove has some harder songs that end on a similar looking hold jump, only to have a set of mines at the very end right after the hold ends. This was the cause of the infamous "800$ BOOM" (and in turn the "800$ " Memetic Mutation), when a player in the finals of a tournament was leading and let his guard down at the last hold, only to hit the mines to ruin his perfect score and lose the match because of it, netting him the 2nd place $200 prize instead of the 1st place $1000.
 * Another case, most likely unintentional, occurs in RED ZONE in DDR SuperNOVA. First of all, the song is 1:48 long when most songs in previous DDR installments are around 1:30. Secondly, the song has what could be mistaken for an outro at 1:29, and the Expert step chart has a left+right Freeze Arrow at that point. In Konami's official US national tournament in 2009, the regional qualifier tournament in Texas saw a player who was leading at that point, hit the Freeze Arrow and thought the song was over, then missed about 4 steps afterwards to lose the match.
 * Less difficult songs only have one last jump at very high speed after you think that the song is over.
 * Custom stepchart maker Family Farce bred his own Kaizo trap in the Tsu...mush series from Hopscotch Mix. Both Tsutsugamush and Tsupseudogamush end with three notes in quick succession, usually charted as a left/right, up/down, left/right. For the third in the series, Tsuhsuixamush, the last jump is replaced with a massive stream of mines, which, through a glitch involving negative BPM, appear instantly and instead of the last jump. If you know it's there, it's trivial to avoid, but if not, have fun trying again!
 * The "Abbey Road Medley" from The Beatles: Rock Band. After going through over 16 minutes of a collection of songs "The End" being the official final song of the medley. Guitar and Vocal players will be WTF-faced after a surprise final song suddenly barges in as they celebrate completing the longest "Guitar Hero/Rock Band" song in history. Not only that but the 27 second song has proven to be more challenging than the rest. Those who made it past "The End" on low health and had not mastered "Her Majesty" will fail out and will want to swear at Sir James there.
 * However, the drummers and bassists get to sit back and enjoy everyone else's pain.
 * Mind, those Genre Savvy enough will avoid the trap: "Her Majesty" is a hidden track on the album, placed after "The End"
 * And players of the Wii version wonder what all the fuss is about, as they got this content in the form of five separate songs instead of one big one. "Her Majesty" is one of the five all by itself, and as such has its own loading screen.
 * In standard Rock Band, the DLC song "Under My Wheels (Live)" seems to end, has Alice Cooper say "Thank you Birmingham!"...and THEN the ending to the song plays. Hopefully you haven't relaxed, especially considering how tough the song is.
 * That's not the only song that has a piece after you think you've played the ending chord. A large number of the higher-end songs have a small solo after the seemingly final chord that can kill you if you, for example, had grabbed something to eat/drink after hitting the note.
 * Not to mention that quite a few Guitar Hero/Rock Band songs have "Cap Notes", where a sustain at the end of the song has a note immediately afterwards, usually on the same fret as the sustain. This can be especially grating if you are going for an FC run and completely forget that there is an extra note after the final sustain of the song.
 * Sometimes used in the Rhythm Heaven series. In Rhythm Heaven for the DS, this happens in the very first game. The screen blacks out and the song seemingly ends, only to keep on going, leaving you with only a tiny peephole to see what you're doing. But Remix 10 from Rhythm Heaven Fever takes the cake. Like in the other games in the series, the song is compilation of all the minigames you've played before, and it ends in a familiar way with the same minigame you started with. After finishing, the music stops and it seems like it's the end, but then it starts up again for an extra bit. Then, the music dies down naturally, your character starts leaving, and the screen fades out... only to start back up AGAIN for one more round.

Roguelikes

 * In Ancient Domains of Mystery, if you kill the True Final Boss wielding anything but a certain magical weapon, the Amazing Technicolor Battlefield swarms you and kills you on the spot. Particularly annoying, as every death is a Final Death, and reaching the boss requires a lot of Random Drops and takes a loooong time.

RPGs

 * Fallout 3 has a rather cruel version in one of the outdoor areas involving an alleyway and some explosive traps. Ordinarily, you can disable traps, and you can even see where the trap begins, which means anyone with half a skull will ordinarily head for the first explosive (a frag mine) and attempt to disarm the others to proceed safely. However, the trap is that there is no way to get close enough without setting off the bombs. In fact, just to twist the knife, the timing of the trap is slightly off from the usual time release most explosions have, and given how the trap detonates, your only option is to trigger the trap and back up very fast, suffering a fair chunk of damage in the process. Otherwise, the trap explosions are rigged to explode in your characters direction, and not moving will almost instantly kill even high level players with good armor.
 * The Mecha-Drago from Mother 3 is a tough fight already. But just to add insult to injury it explodes on death, causing your health to rapidly tick down during the post-battle summation sequence, and, if you don't mash the A button fast enough, actually die and have to do it all over again.
 * There are actually several enemies that do that in the Mother series, like the Territorial Oaks and Nuclear Reactor Robots.
 * Lunar: Silver Star Story Complete: You defeat the Magic Emperor You go to walk up the steps to your girlfriend  You forget to  before getting up there. ZAP. Particularly annoying since, in an earlier dream sequence, you had to keep advancing towards Luna while she throws lightning bolts at you to complete it, and many players assumed the same principle applied.
 * In the original Saturn version, it was possible to make this Unwinnable if you had transferred the ocarina into someone else's inventory (since Alex is all alone when he goes up there). This was fixed in the PS 1 version where it's impossible to take it out of Alex's inventory.
 * Not completely fixed. You could transfer the Ocarina to Nall in the demo version. Then transfer that save to the full game. Oops!
 * This "trap" is derived from the actual "original" release of the game on the Mega Drive, though Alex played a harp rather than an ocarina. The player does get a bit of a warning by way of non-lethal (but still HP damaging) zaps, but failure to play the harp before reaching Luna always results in a final fatal strike.
 * Thankfully, Harmony spares you - all the lightning ever does is knock you down.
 * It spares you in two different ways, since the inventory is now Bag of Sharing style.
 * The cutscene of the dragon boss dying at the end of the first area in Phantasy Star Online notably has you retain control over your characters. This is because it can (and likely will if it's your first clear) fall on them during its death throes, possibly killing them. In fact, the Ultimate-difficulty version of this is the most powerful attack in the game.
 * Done as a Shout-Out in Phantasy Star Zero with Reyburn.
 * Merikle's instant death on contact spit says "Hi."
 * So does Humilias' last drive. This is less That One Attack as it is the cap to That One Boss. Getting run over by a hovering drill car makes the giant robot anal rape that much harder to swallow.
 * At a point in Final Fantasy XII, the player slogs through a long dungeon and a difficult battle in a chamber, only to get to the other side and find a save point waiting. But then you approach the save point and SURPRISE! It's a monster!
 * The same happens in Chrono Trigger in the 2300 A.D. sewers, where the "Ding!" of the save point catches the attention of some merman enemies. If you didn't go through here on your first trip through the future, however, you'll likely be at a high enough level that it's not all that deadly.
 * Monster Hunter had this, though it doesn't involve starting over. If you capture a medium or large-sized monster, like a Wyvern, it can do damage to you if it falls on you. If you have low enough health to get knocked out by this, you will lose 1/3 of your Reward, even though the quest completes itself about 5 seconds later. This can also happen if you've killed only 1 out of 2 or more Wyverns in one quest, thus not giving you a Quest Complete.
 * Mario & Luigi: Bowser's Inside Story has an example with the Dark Star's Taking You With Me attack. You see, once you beat him, the battle doesn't just end, he turns into a black hole and tries to suck in the player characters, forcing you to hammer A or B to get Mario and Luigi off screen. Fail to do so and you probably will die from the huge damage this final attack does (unless you're at a really high level or have defense-aiding items).
 * Final Fantasy VI had the Magic Master. Knock out all its HP, it casts Ultima, Rocks Fall Everybody Dies. Four possible escapes: Rasp and Osmose out all his MP (so no MP for the spell); have someone with the Reraise effect (triggers automatic revival on KO); summon Quetzalli to whisk everyone away for a jump attack (as long as one person is still in the air when he casts Ultima, they'll survive), or level until you have max life and make sure you're completely healed before he casts Ultima.
 * If you have the wrong party in endgame Oracle of Tao, even if you win the final boss during a plot event does a final blast where he tries to kill off everyone in the universe. You get a bad ending even if someone survives, just for not qualifying for a better ending, but if everyone dies... the ending is very depressing.

Run And Gun

 * After a fairly easy boss fight, the fourth stage boss of Gunstar Heroes throws a magical gem (the MacGuffin you've been searching for) to you. Savvy players will wonder: 'Doesn't this sequence usually happen in a cutscene? Why do I still have control of my character?' Less savvy players will be blown the hell up. Beating on or shooting the boss's grovelling form a bit more (or a lot more) induces him to cough up the real gem.

Shoot 'Em Ups

 * In many Shoot Em Ups, after you beat certain bosses, such as Gradius II's first boss and Raidens second boss, their exploding wreckage remains on the screen for you to crash into. Also, with Raidens third boss, the screen keeps scrolling and enemies continue to spawn and attack after you defeat it.
 * 1943 for the NES has every ship boss at the end of a level. On defeat, their control tower will explode into harmful wreckage. Ths trope can apply to the the Final Boss, you're probably out of fuel (one more hit will down you), and you're relieved that you managed to beat it- just remember to stay far from the thing or shoot the damn wreckage as it comes.
 * Musha on the Genesis can kill you after the apparent end of the game, though you get a lot of points at that moment and will probably end up with an extra life, so even if you don't notice it you probably won't lose the game.
 * In the Touhou series, very few of the games wipe the bullets as soon as a boss is defeated. Before Mountain of Faith, the player was given invulnerability during bosses' defeat explosions. However, the game engine was rewritten for Mountain of Faith and the invulnerability was left out, so the trope is in full force from MoF onwards. This makes it possible to get hit by a bullet and die after the final boss has just been defeated.
 * It's even worse during the final boss battle in Subterranean Animism because the last card of the final boss sucks you in while forcing you to avoid bullets shot by her and coming from behind you. When she's exploding, the effect still lingers but your player character moves in slow-motion so you have to carefully adjust your position one last time or use a bomb. Otherwise...
 * In Perfect Cherry Blossom, the Berserk Merlin Game Breaking Bug, which desynchronizes her from the other two bosses during the last spellcard, will also cause her to kill you during the ending conversation and stage results, when the player can't move.
 * In Star Fox 64, the boss of Zoness can still hurt you as it goes down. Getting hit by its final laser will only do a little damage, so unless you're on the verge of death, it's no big deal. Getting hit with debris from the spiked ball cannon flying off, on the other hand, will wreck your wings in Expert mode--just like every other hazard.
 * In Gradius IV, after you defeat the already That One Boss boss of the Cell Stage, it turns into the Zelos Force from Salamander and fires an omnidirectional beam spam before exploding.
 * After the first loops of Gradius games, almost every enemy will fire bullets after the player shoots them down, including bosses. The frequency and density of these bullets increase with each loop.
 * After defeating the final boss in Salamander, the player must pilot the Vic Viper to safety past a series of quickly closing gates that leave you only just enough room to fly through. If you are not at the top of the screen for the third to last one, it will close completely before you can react.
 * And in the NES version, if you don't destroy both parts of the boss, you get sent back to Stage 4.
 * The arcade version of Gradius III also has a high-speed Escape Sequence at the end. If you fail, you get sent back to the regenerating cell walls minus all your powerups.
 * After defeat, Guardian's Knight in Thunder Force V would fire a HUGE ASS Wave Motion Gun right before he explodes into pieces. If you didn't stay at the top or bottom of the screen, there goes your life (and your equipped weapon, and all your CRAWs).
 * The second boss of Super Spy Hunter charges towards you after you defeat it and will instantly kill you if it makes contact.

Simulation Games
"Drayman: We owe you our lives, Phoenix!
 * In Crimson Skies you can crash during the final moments of the end battle after you achieved the victory conditions. The ending movie and credits will play but then it jumps back to making you replay the mission as though you lost and were retrying it. You won't get anything for beating it until you finally beat the mission without crashing.
 * During almost all of the Ace Combat games, it is totally up to the player to NOT crash after the 'Mission Accomplished' sign pops up on the screen. This even includes as the screen is fading to black. Subverted in AC2, though, where crashing would only cost you credits but not victory.
 * Often times missiles fired just prior to the "Mission Accomplished" screen are still hot and capable of tracking the player aircraft, despite the enemy planes that just fired them being neutralized. On certain missions on higher difficulty settings where enemy accuracy and damage is increased, players need to continue to perform evasive maneuvers throughout the "victory lap" portion of the mission just to avoid being shot down.
 * While AC2 subverts this trope, its remake Ace Combat Assault Horizon Legacy doesn't. Which can lead to cases like this:


 * player dies*

Keynote: NO! PHOENIX DOWN!"


 * Tutorials are especially prone to this, as they tend to lock the controls after completing the objectives so the trainer guy can ramble on for a bit, quite possibly resulting in your helplessly smacking into a mountain (which forces a restart, naturally). Some of the games aren't even programmed to activate auto-pilot while this is happening. Hope you weren't aimed for the ground when the game took over.
 * In Ace Combat 5, a programming bug meant that occasionally some enemies would still be active after the mission was accomplished. If these enemies shot you down, you failed the mission.
 * This is especially notorious during the mission where you have to . Your enemies by the end are YF-23s, pretty much the only planes that actually act like stealth planes in the game. Usually, when you finish a mission, you can at least see your radar before the Mission Accomplished screen pops up, so you know where the other planes are. Here, you don't know if there are any YF-23s left. Coincidentally, YF-23s have an odd tendency to go 300 feet behind you and fire missiles only then. Also, if you fail at the very end, you have to do the mission all over again.
 * A hilarious example in a speed run of the Tunnel Vision stage in Ace Combat 3, where the player is going so fast at the end that he crashes into the wall at the end of the tunnel that the sky texture is painted on.
 * Air Force Delta Strike had this for several Airstrike Impossible missions where you must let the Enemy Chatter script finish, then it would fade to the victory screen. This could get frustrating where said missions would be instant death if your plane touches anything. It's realistic for a plane going Mach 1 to be destroyed if it contacts a hard surface; it's not realistic for a VTOL in hover mode to suffer instant death for drifting--slowly--into a wall.
 * In Superman 64 you can die during the "Superman wins" screen until you press start. This is not an intentional invocation of this trope, just infamously broken game programming. Note that you can invert this. Even if Lex Wins, you can sometimes wait long enough for the objectives to complete themselves. Then Superman Wins.
 * In Hawx 2 it's possible to crash or be killed during cutscenes where you have no control or even sight of your plane.

Sports Games

 * In Punch Out for the Wii, Aran Ryan literally throws (well... swings) one last punch (well... boxing glove on a rope) every time he's knocked down during Title Defense. Fortunately, the cheap hit can't knock you down and thus you can't lose directly from getting hit by it. In fact,
 * It's not the first time he's done it: in the SNES version, he'd fake falling down every time he was hit with a KO punch, then turn, try to grab you, and launch a flurry of punches.

Stealth Games

 * Assassin's Creed II has a variation of this during the Emilio Barbarigo assassination. Basically Emilio has a boat on its way to take him out of the city, and you have to infiltrate his home and kill him before he escapes. Naturally, the easiest method would be to board the boat and wait for it to take you to him, right? PROBLEM: The moment the boat docks, the game already counts it as a Mission Failed, so even if you assassinate him before he touches the boat, the game will still tell you "Emilio has escaped" and desynchronize you; although you're still treated to the post-assassination speech.

Survival Horror

 * In Resident Evil 4 the Gigantes will fall forward after the final blow. If Leon's close enough when this happens then you have to do a Quick Time Event to dodge. Also, after a player defeats the first boss, Del Lago, and has perhaps laid the controller down to enjoy the hard earned cut-scene, there is a one-button action prompt that will result in instant death if missed.
 * There's also another point where you fight two of them at once. You can lure them over a trap door that is right over molten metal. However if Leon is near the trap door after you sunk a Gigantes in, it'll grab Leon and drag him into the pit.

Third Person Shooters

 * In the first Splinter Cell game, the end of one of the late-game missions tasks you with protecting several hostages, possibly with the help of hacked turrets. After you kill a group of mercenaries, their boss and a few of his friends come down to finish the job. Your objective is to kill him; it ideally doesn't matter whether his mercenaries die or not. However, if you don't, you can die during the transition to the mission-complete screen.
 * Transformers War for Cybertron. So you've just blasted  within an inch of his life, and he's hanging to the edge of a large hole he made in his anger.
 * Due to how the engine of Gears of War renders cutscenes, it's possible to invert this trope. For example: if an opening cutscene features randomly-fired mortar shots, and one of them lands close enough to one of the players, they could instantly die when the cutscene finishes and the action begins.

Turn Based Strategy

 * Fire Emblem: The Blazing Sword pulls one in the hidden chapter "Genesis". The boss of the chapter is a cowardly non-combatant who forces you to navigate a maze of small rooms to get to and kill all the enemies. Should you finally hit the end of the maze and unlock the door to his room, Enjoy!
 * Oddly,
