Try to avoid the zombies that you encounter while you get to the supply center as quickly as possible. Grab the supplies you need and then get back to your safe house as quickly as you can. The car is difficult to maneuver because it is very touchy. There is an arrow above your car that tells you which way you need to go to get to the supply center. Each level is timed and if you run out you must start the level over. There are very bright lights on the front of your car to help you see the road and any zombies that might try and block your way.
