Zombies have sprung up everywhere and are overrunning the population very quickly. The main character sees his only chance of survival as getting out of town. A little ridiculous at first because your vehicle starts out with very little gas. However, you earn money for the distance you travel and how many zombies you take out in a run. The starting and stopping of the game will get longer and longer as you upgrade your vehicle, if you can be patient enough. Things are sure to get better once you save enough money to get a huge machine gun attachment.
