Day and night the zombies are coming. So there are few guns for use to send them again into the world of dead. Good aiming is your job. Good action shooter where you try to survive.
FPS gives you fine view to all the incoming zombies. There is nothing else to do than shoot them and live another day.
The ammo is unlimited but loading your gun takes some time. The graphics part is good and more types of weapons can be achieved as well. The points you get can be used for defense and you can even search for more survivors.
