It's time to impale some zombies again! Kill the zombies by launching them into spikes, saw blades, hooks, and other sharp things. Each sharp weapon has a red light, which will light up when it pierces a zombie. A level is complete when each weapon's light is lit. You have an infinite supply of undead projectiles, but you will lose points for each shot. If you finish all 50 levels with enough points, you will unlock 20 bonus levels!
