Survive as long as you can!
With a choice of six maps and three difficulties!
Zombies spawn faster, run faster, as spawn more frequently the harder the difficulty you chose. The amount of lives and bullets you have also decrease with the harder difficulties. Zombies randomly drop: ammo boxes to restock your bullets, hearts to gain one life and a bomb to kill all zombies! Ammo boxes also spawn in the middle of the map if you run completely out. Hearts also spawn in the middle of the map if you are down to your last life.
