In Stay Alive you are fighting against a zombie invasion from a bird's eye view. Use the arrow keys to move around and keep out of the way of the zombies. There are little zombies which only take a few bullets to kill and there are bigger zombies that take considerably more firepower and excrete a green ooze you don't want to get near. As you kill more zombies, you earn gold which you can use to buy better weapons which will make killing a lot easier! Just stay alive as long as possible and earn new weapons and then the final weapon is a solider you can place on the roof to cover you as you try to Stay Alive!
