You are a soldier of an army which has lost communication with one of their top secret facilities. You and your team are going to go there and check what happened. You will have two more soldiers with you. Once you enter the building, you will see people killed there. You and your troop will inform this to the HQ. Then, suddenly out of nowhere, zombies will come and attack to kill you. Now all things are clear to you. Enemies have occupied this area and you have a harder job in hand now.
