Zombie Flick is one of the more original games I looked at. As with other zombie games, you're the lone survivor fighting off hordes of the undead. But this one lacks guns or any sort of traditional weapon.
Zombies come at you from all directions, and all you have to throw at them are items from the pile of junk you're standing on. You fight off the moldering crew with rolls of toilet paper, old guitars, and an occasional cat. The targeting is also interesting; you simply swipe a line between the object you're holding and the zombie you wish to attack.
