In this game, you're a survivor on a battlefield full of dead and wounded. You're the last one left, and your mission is to stay alive as long as you can. Your health is slowly getting lower, and you have only one weapon left: a gun. You need to shoot the dead and wounded as much as you can and try to survive. You have to shoot the zombies one by one, and you need to make sure that you're the only one left. The more you shoot, the more your health will decrease, and the more dead and wounded you will encounter.
