Blast Chamber Description:
Your mission is simple: survive the game. You're thrown into a chamber with a load of highly explosive C4 strapped to your body. The countdown begins as you scramble, both against opponents and in solo-player modes, through an obstacle-filled, lethal chamber. Your goal is to snag the crystal, gain control of the game, and stay alive. The Chamber rotates, so become floors and floors become ceilings. Watch out for spikes, electrical fields, lava pits and other lethal traps! And keep an eye on that clicking timer. Lose control and you're toast.
