Ugly zombies are back and you are humanity's hero to keep the only hope-the Holy Vessels safe. But beware, ammo is limited so you will have to get crafty and use the straight bullets, grenades, split- and buckshots in the most effective way possible to survive all the missions.
Besides, you must swipe out the colored accretion before the zombies become to strong to deal with. You are the only hope, stay alive!
