The setting of the game is in an abandoned country and there are zombies everywhere because they got infected by the Z virus. One day while you are on the roof of a water station, you saw your last hope; it is a helicopter. Finally, this is your chance to get out of that crazy place and be with someone normal for a change. So, you find a car and ride to the helicopter.
There are lots of zombies on the road. The game rewards you with money depending on how much distance your car traveled. So, the further you traveled the better since you will get more money that you can use to upgrade or buy a much faster vehicle.
