The whole world is now in chaos as the zombie apocalypse is now upon us. After destroying one city, the zombies set their eye on another city. However, your farm is on their way. You can hide since they are not after you, but that would be too cowardly for you, so you decided to exterminate any zombie that comes your way. Your goal is to exterminate the zombies attacking your farm. The zombies would be tougher as you go from one level to another. It would be advisable to buy better equipment or at least upgrade your existing equipment to be able to fight the stronger zombies ahead.
