GlitchStorm

GlitchStorm is a fast-paced, online multiplayer arena shooter, where you play as robots, androids or cyborgs. You need to learn how to hack your enemies and surroundings fast, or you wont stand a chance in the tournament.

The game is set in the future, long after humans ruled the earth. There are still a few of them here and there, but they're hard to find nowadays. Well they did this to themselves, so good riddance.
