MicroBot -- without you. If you're still looking to play MicroBot on your PlayStation 3, the game's heading to PlayStation Network tomorrow, January 4, for $10.
MicroBot has you piloting a tiny ship inside of a human body (read: Innerspace), destroying diseased enemies and working with a partner to complete objectives. We'd suggest meeting some new friends before jumping into the co-op, though. These fair-weather folks don't sound very nice and, frankly, you deserve better.
