''EOE: Eve of Extinction'' is a BeatEmUp game developed by Yuke's, published by Creator/EidosInteractive, and released in early 2002 for the Platform/PlayStation2. The main gimmick was the ability to switch weapons mid-combo.

The story concerns a young man named Josh Calloway, whose girlfriend Eliel is transformed into a type of weapon known as a "Legacy". As a result he turns on his former employers, the Wisdom Corporation, and goes after his former boss Agla in order to recover a chip which will reverse the process.

!!''EOE: Eve of Extinction'' contains examples of the following tropes:
* AerithAndBob: The bosses clearly just have codenames, however our hero Josh is opposed by the likes of Zera and Agla and aided by his girlfriend Eliel.
* BagOfSpilling: Roughly 2/3 of the way through the game, there's a level where a boss steals your weapon chips and hands them out to his EliteMooks.
%%* BarehandedBladeBlock: [[spoiler:Zera]] performs one in a cutscene. It's the first sign that she's not quite human.
* BlowYouAway: The Boomerang's Legacy Drive stirs up powerful wind.
%%* CorruptCorporateExecutive: Agla is a textbook example.
* DeflectorShields: One of the weapons is an energy-bolt-shooting crossbow whose Legacy Drive heals and shields you.
* DoppelgangerAttack: The Broad Sword's Legacy Drive creates a copy of yourself to distract enemies.
%%* TheDragon: Zera. Played with in that [[spoiler:Agla wields her rather than just having her fight the player]].
* ElementalTiers: Each weapon has a specific element and is also more powerful than the one that came before it.
%%* EnergyWeapon: All Legacy weapons look like this.
* EquippableAlly: The Legacy weapons are made by converting a human's neural structure into an operating system, the most powerful ones being Eliel and [[spoiler:Zera]]. Although it's not made clear if the former is an actual example of this, if she can project some sort of hologram or if the cutscenes show her in humanoid form for convenience's sake, [[spoiler:Zera]] certainly is.
* FinalExamBoss: [[spoiler:Agla is invincible to any Legacy weapon other than the one that matches the color he changes to.]]
%%* GoodOldFisticuffs: You had the option...
* GravityMaster: The Giant Axe's Legacy Drive creates a burst of intense gravity.
* InvincibilityPowerUp: The Tonfas, which you get from Raven, Legacy Drive renders you invincible for a time.
* MacGuffin: The memory chip which will turn Eliel back.
* MakingASplash: A pair of Katars, Legacy Drive unleashes a blast of water.
* TheManBehindTheMan: [[spoiler:Agla's assistant Zera turns out to be the original Legacy weapon.]]
* MegaManning: You collect each different weapon mode's chip by taking it from the boss who was carrying it.
* MorphWeapon: The game's main attraction is the ability to switch Eliel's forms between several different weapons mid combo. Each one also had its own elemental powers and special ability.
* OmnicidalManiac: [[spoiler:Agla's EvilPlan is to use the power of his and Josh's weapons to destroy the world and himself with it.]]
* {{Orichalcum}}: Part of what makes up the Legacy weapons. It's awkwardly pronounced in-game as "[=OriKILLUM=]" and "oRICKulum".
* PlayingWithFire: The Sword's Legacy Drive creates a burst of fire.
* PoweredByAForsakenChild: All Legacy weapons need to have a human soul bound to them.
* PressXToNotDie: The game has cutscenes like this. Failure normally just knocks off a bit of your health bar and forces you to try again.
* ShockStick: The Rod. A blue bo-staff sort of thing, Legacy Drive summons lightning.
* StuffBlowingUp: The Twin Blades. A pair of swords which resemble the ones EliteMooks wield, Legacy Drive causes an explosion in front of you. You only get to use them in a NewGamePlus, though.
* TimeMaster: The Snake Sword's Legacy Drive freezes time.
