As a professional military officer, you must protect the safety of civilians in any situation. But lately this has become increasingly difficult due to the zombie invasion. It has become increasingly difficult to hide from the living dead; they attack even at night and make their way into underground shelters. In the game Call of Duty: Zombies (Demake) you have to protect the entrance of one of the bunkers. The door to it is strong and thick, but can give way before the onslaught of a huge crowd, so you must destroy all the undead that move towards you in Call of Duty: Zombies (Demake). It’s more difficult to do this in the twilight, but there is no other way out.
