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.
No relation to End of Evangelion.
EOE: Eve of Extinction contains examples of the following tropes:
- Aerith and Bob: 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.
- Bag of Spilling: 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 Elite Mooks.
- Blow You Away: The Boomerang's Legacy Drive stirs up powerful wind.
- Deflector Shields: One of the weapons is an energy-bolt-shooting crossbow whose Legacy Drive heals and shields you.
- Doppelgänger Attack: The Broad Sword's Legacy Drive creates a copy of yourself to distract enemies.
- Elemental Tiers: Each weapon has a specific element and is also more powerful than the one that came before it.
- Equippable Ally: The Legacy weapons are made by converting a human's neural structure into an operating system, the most powerful ones being Eliel and 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, Zera certainly is.
- Final-Exam Boss: Agla is invincible to any Legacy weapon other than the one that matches the color he changes to.
- Gravity Master: The Giant Axe's Legacy Drive creates a burst of intense gravity.
- Invincibility Power-Up: The Tonfas, which you get from Raven, Legacy Drive renders you invincible for a time.
- MacGuffin: The memory chip which will turn Eliel back.
- Making a Splash: A pair of Katars, Legacy Drive unleashes a blast of water.
- The Man Behind the Man: Agla's assistant Zera turns out to be the original Legacy weapon.
- Mega Manning: You collect each different weapon mode's chip by taking it from the boss who was carrying it.
- Morph Weapon: 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.
- Omnicidal Maniac: Agla's Evil Plan 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".
- Playing with Fire: The Sword's Legacy Drive creates a burst of fire.
- Powered by a Forsaken Child: All Legacy weapons need to have a human soul bound to them.
- Press X to Not Die: The game has cutscenes like this. Failure normally just knocks off a bit of your health bar and forces you to try again.
- Shock Stick: The Rod. A blue bo-staff sort of thing, Legacy Drive summons lightning.
- Stuff Blowing Up: The Twin Blades. A pair of swords which resemble the ones Elite Mooks wield, Legacy Drive causes an explosion in front of you. You only get to use them in a New Game Plus, though.
- Time Master: The Snake Sword's Legacy Drive freezes time.
