Backrooms: "SCP 173"

You will find yourself in an endless maze of randomly generated utility rooms. One theory says that it is impossible to get out of the back rooms, and it's up to you to find out. Try to blink less, because somewhere within these walls lives the monster number SCP 173, who escaped from the SCP Foundation. This terrifying adventure will make your heart beat faster, like the screams of the disturbing loneliness of the walls and the frightening rattle of an object of unknown origin. Behind the scenes are terrible corridors covered with a yellow old wet carpet, the walls in it are pasted over with yellow wallpaper, and on the ceiling there are square fluorescent lamps. God forbid you hear that something is wandering around, because the monster probably knows about you.
