This is a cool game!

First, its not a huge file, so it wont eat up your storage.
Second, its hilarious.
Youre driving a car down a deserted road, and zombies are jumping on you as you drive by. And there are only 2 ways to get them off: shoot them, or knock them off by smashing your side up against an overturned car in your path.
Car upgrades for driving a certain amount of accumulated miles (I currently have the Hummer), and weapons upgrades.
Very cool game.
