Pop as many zombies as you can!
Judge both your speed and direction and throw your axe to pop as many zombies as you can. You have eight sections of levels all with a certain amount of stars to be collected to unlock each of the level areas. The more zombies you manage to pop the more stars you are awarded with at the end of each level. Face different types of zombies along the way, each one with different effects when they pop. Girl zombies are explosively hot, Frankenstein zombies will zap and become invincible for a short period of time and cop zombies will change size.
Remember though you have to earn a specific amount of stars to progress to different level areas and conquer all 80 levels.
