The virus has broken and you are the only survivor left on earth. The zombies are hunting for you and you are trying to stay alive as long as you can. Equipped with several weapons, you are holding your line of defense and are fighting the incoming waves of zombies. Use the numeric keys to select from a range of weapons. Hit the space key to reload and the mouse to aim and fire towards the zombies. Try to aim for the head to make a quick kill using fewer shots. If you are able to survive all the levels, you will be able to unlock new weapons and monsters to fight with.
