Something has gone terribly wrong. Your orders: stop the spread of the zombie apocalypse. With your trusty saw-blade and paddles, survive on your own or with the help of a friend through endless waves of zombies. Collect awesome powerups. Get combos. Get a high score. Make zombies go splat!
The blade speeds up over time. If you keep it bouncing back and forth without missing it, eventually it'll light on fire for extra kill points!
