Chaos Legion

"Tis the darkest Glyph thou bearest. It sacrifices stray souls to summon unearthly force. Unearthly force shall obey and serve thee. 'Tis named "Chaos Legion"."

Hack 'n slasher game created by Capcom, released in 2003 for the PlayStation 2.

Sieg Warheit and Victor Delacroix used to be the best of friends. Unfortunately, Delacroix has fallen into The Dark Side--Seig, Delacroix and their lovely lady friend, Siela, were trying to seal away the Dark Spirit Azrail as it tried to escape. For some unknown reason, Sieg murdered Siela right before Delacroix's eyes. Or did he really...?

Now, in the present day, Sieg is in hot pursuit of Delacroix, who plans to gather the seals that hold back Azrail in order to release it, which he thinks will reunite him with Siela. Sieg will not have it easy--Delacroix has summoned many hordes of demons who want nothing more than to kill Sieg. However, Sieg is a "Knight of the Dark Glyphs" and a "Legionator". A Legionator is one who has the ability to summon "legions", powerful and massive creatures that will fight alongside their caller, defending and attacking when commanded to do so. Armed with a sword and his legions, Sieg is more than ready to discover the truth.

This game provides examples of:
 * And Now for Someone Completely Different: Arcia, the gunslinging maiden is playable for one stage, and can be unlocked for play on all stages.
 * A Taste of Power: Thanatos, the strongest legion, is available in the tutorial stage, and is broken into pieces once the stage is completed. Recollecting the pieces is something of a plot point, and well worth it.
 * Badass Longcoat: Sieg.
 * Bad Ass Cape - Delacroix.
 * BFS
 * Bishounen Line: The final boss shows this.
 * Bottomless Magazines: Arcia's pistols never run out of ammo, although her Energy Sphere shots have a limit.
 * Bullet Time: Thanatos' Assist skill, Ignorant Masses, slows down everything except Sieg, while Thanatos himself rains homing Beam Spam on the enemies.
 * Charged Attack
 * Crosshair Aware: Some bosses will give you red markings on the ground to indicate where they will strike next.
 * Death From Above: The Flawed Legion attacks in one of two ways - a quick dash followed by a swipe before backflipping to safety, or by leaping up and coming down on the enemy claws first, spinning like a drill.
 * Death of a Thousand Cuts (the Guilt Legion)
 * Deliberately Monochrome: Almost, anyway. The color palette is very, VERY desaturated; the city is various shades of white-gray and brown-gray and only magic and your own summoned demons have any kind of bright colors (and are usually just one color in varying degrees of brightness).
 * Flunky Boss: Every one of them.
 * Gotta Catch Them All: The pieces of Thanatos.
 * Gratuitous French: Victor Delacroix.
 * Gratuitous German: Seig Wahrheit.
 * The Gunslinger: Arcia.
 * Guns Akimbo: Arcia wields two small silver pistols, one in each hand.
 * Hack and Slash
 * Idle Animation: Even your legions have one!
 * Implausible Fencing Powers: The Guilt Legion (swordsmen) are like this. When repeatedly ordered to attack, they are relentless, merciless, and make julienne fries!
 * Improbable Aiming Skills: Arcia only misses if you deliberately aim at nothing; the Malice legion only misses (for a couple of seconds) if you're aiming for them, although they do have a range limit for their rapid-fire attack.
 * Infinity Plus One Sword: Thanatos when maxed out. Any of the Legions are powerful at max stats, but Thanatos is so far above them all that it gets a little ridiculous when you fight Azrail (3 hit kill). In fact, Thanatos is so ridiculously powerful, that the main strategy for beating anything in the game when you max out all of its stats is: Lock-on monster, use Ignorant Masses, run up to the enemy as it is bullet timed and carpet bombed, then just Attack Attack Attack. And the last part is optional, because sometimes all targets are destroyed before you're given even a chance to close in.
 * Kick Chick: Arcia. She uses her guns strictly to pump lead into enemies; if she has to go melee, she lets her Combat Stilettos do the beating.
 * The Legions of Hell: Seig's Legions, and the demons that Victor summoned to stop him.
 * Last Name Basis: Delacroix is never referred to as Victor in-game. Not even by Siela.
 * Luckily My Shield Will Protect Me: Arrogance Legion
 * Also some enemies, although their shield don't protect them from Blasphemy.
 * Made of Explodium: Blasphemy Legion, which are demonic bombs, can be kicked and explode upon enemy contact.
 * Mook Maker (the aptly named Monster Generators)
 * Nintendo Hard
 * Ominous Latin Chanting: This trope is the lifeblood of the soundtrack; most of the regular stage music has a choir tucked away in the chords, doubly so when you bring a legion out. And if, somehow, you manage to clear the stage without ever calling on them, the boss fight song will make up for it.
 * The stage 8 music adds Ominous Arabian Chanting instead.
 * One Hit Point Wonder: American Super Mode, in Japan its just your enemies.
 * One Winged Angel
 * Painted On Shirt Sieg's shirt is so tight that he may as well not be wearing a shirt at all.
 * People Puppets:
 * Powered By a Forsaken Child:
 * Rain of Arrows: The Malice Legion's attacks are like this.
 * Rank Inflation: AAA+ rank (!!)
 * Redheaded Hero: Sieg. Allll the way.
 * The Right Hand of Doom - Sieg's gauntlet seems to be the main conduit for summoning his legions. Capcom sure has a thing for magic arms (God Hand, Onimusha, Devil May Cry, etc).
 * Scarf of Asskicking: Arcia.
 * Sdrawkcab Name: The forbidden city of Yzarc.
 * Sealed Evil in A Can: Azrail
 * Summon Magic: The Legions
 * Title Drop: See the opening quote, which is the first line in the game's cinematics.
 * Tome of Eldritch Lore: The Apocrypha of Yzarc
 * Two Guys and A Girl: Sieg-->Delacroix-->Siela
 * Variable Mix: Every stage has a secondary song that plays when a Legion is currently on the field.
 * Weird Moon (the legendary Red Moon)
 * White Haired Pretty Boy (Delacroix)
 * Word Salad Title
 * Wrestler in All of Us: The Hatred legion works on this trope, and even has an ability to catch an enemy's attack before putting a size-appropriate hurt on them: smaller foes tend to be knocked over and mashed into the ground, while some of the few enemies larger than them usually get a single (but painful) slam. They also like giving a "Come get some" style taunt after being ordered to attack.
 * X Meets Y: Devil May Cry meets Gauntlet
 * Zettai Ryouiki (Arcia)
