SlingSkull Zombies: Graveyard Shift is an action cartoonish game where your goal is to hit and destroy every zombie in every level by hitting them with a skull projectile.
Your weapon is a huge slingshot and your ammo – skulls. The zombies are trying to eat your brains and there is only one way to stop them from doing that, and that is hit and destroy every one of them. As the game goes further, the levels get harder and the zombies get harder to hit.
Aim, release and shoot to kill. Again.
