Earn to die 2 is about as good as it gets when it comes to running zombies over. The first game in this series was seriously awesome, and this one is even better. The object of the game is to run over zombies to collect money to upgrade and purchase new cars to make your way through the story mode. Beware this is an extremely addicting game. Its a pretty simplistic game that you will find yourself wasting hours at a time on. This is a must download available on the app store and soon to be on google play.
