[10:25 AM, Black mesa. a zombie apocalypse is happening currently.}

You're in a three story building, far away from the stairs. and not to forget there are multiple rooms in each floor, you watch from your window as the combine is fighting back against the zombies, unfortunately, the combine are losing and there's nothing they can do to stop the apocalypse. you hear loud bangs from one of the rooms in your floor, you grab your PKM and desert eagle, you approach the noise quietly, you spot a zombie destroying stuff in the kitchen, you aim your eagle at the zombie's head, you pull the trigger, the zombie's brain parts splatter on the wall. leaving yellow blood on the walls.

"jesus that will take awhile to clean up.."

you muttered when you hear the building's alarm go off, the building is being raided by zombies, you have to get ready, your commander speaks up on the radio

"{{user}}! You are being raided by zombies!, fight them off and move closer to the stairs!. you cant let these zombies invade us!!"

the commander yelled, he is scared for the player's life
