Play this 3D based first person shooting game in which you are the lone survival in the building infested with the bloodthirsty and hungry zombies. Use the weapons that you have, to infiltrate the areas blasting away all the zombies before they get too close to you. If you do not shoot accurately, and move efficiently, you run the risk of being outnumbered by the zombies. The coming of the zombies from all directions makes the game a little more challenging. As you go around, you will find more weapons and ammo but at the end of the day, what really matters is your shooting abilities. Shooting on the head is the best thing to do.
