Love this game. It starts out at casual fun, but develops into something you can't put down. I've played (and finished) the game on both Steam, PSP and PS3, and all were equally good. Describing the actual game is kind of redundant as the video is pretty descriptive. But the key gameplay is starting chain reactions and upgrading your (and the zombies') abilities.
