The Backrooms: Found Footage

If you're not careful and noclip in the wrong areas, you'll end up in the Backrooms, where it's nothing but the stink of old molding carpet, the madness of mono-yellow, the endless background noise of fluorescent lights at maximum hum-buzz, and approximately a billion square miles of randomly segmented empty rooms to be trapped in. If you hear something wandering around nearby, it sure has heard you.
