Wakle Skade: A young blond man who is the only playable character at the beginning of the game. His handgun has only one primary attack: rapid-firing blue energy bullets. He has two special abilities, both of which are defensive. One is the energy shield and the other is a "stop bullet" that can freeze the enemy for a few seconds.
Kard Berdish: An ex-officer of the mysterious corporation that seems to be responsible for the monsters. He has white hair, wears a military uniform, and carries a multifunction rifle that includes a laser rifle, flamethrower, homing-missile launcher, and grenade launcher, as well as two devastating special attacks.
Steyr Harquebus: A dissident fighting against the corporation. She is a small teenage girl with a long-barelled minigun that is taller than she is. She has only one primary attack, but her four special moves more than make up for this shortcoming.
Dee Van Feng: A cyborg teenage boy with long white hair, created by the corporation. Dee carries a pair of Uzis.
Each of the four characters has a unique story, which mostly involve the same levels as the other characters, but in a different order, and with some elements shuffled around. Only Wakle is playable at the beginning; other characters must be unlocked by performing specific actions with available characters.
