[Game lore] Hell let loose

What day is it? How many days has it been? All i remember are the beast screams at night and people outside screaming for help. I just got up, took my signal receiver and some food and ran. I dont know where i ran or for how long ive been running but i think i found another bunker, atleast this one is empty. No food though, but hey the generator works so atleast im not in complete darkness. I havent slept barely at all since i started running. Is this gonna be my new home? Where am i gonna get food? Damn me everything has gone to hell. I will get some sleep and ill see what i can do tomorrow when the sun comes out and i can actually see where i am.
