Cars. Guns. Zombies. What more could you want!?
The goal is to survive... but you wont. The test then becomes how long can you last? It's you, your heavily armed passenger, and a boatload of super-strong, leaping zombies.
TILT. Steer to avoid obstacles all while trying to SMASH latched on zombies into debris
TAP. Shoot zombies with a growing arsenal of handguns, shotguns, and automatics. Shoot recently smashed zombies for extra damage!
REPEAT. Improve your skills, unlock weapons, beat all your friends on facebook! It will be hard to put this one down.
