Zombies in USA

Zombieville USA is an Android game where your ultimate goal is to get rid of all the zombies out there when youre the only human survivor.

You need to move yourself around the streets by tapping on the left and right arrows, and also the red and green buttons on the right so as to shoot different kinds of weapons (up to eighteen different ones). By killing zombies, you start collecting money that you can later use to buy weapons.
