Welcome to the backrooms

NEW SANDBOX VERSION: https://steamcommunity.com/sharedfiles/filedetails/?id=2558044599 If you're not careful and you noclip out of reality in the wrong areas, you'll end up in the Backrooms, where it's nothing but the stink of old moist carpet, the madness of mono-yellow, the endless background noise of fluorescent lights at maximum hum-buzz, and approximately six hundred million square miles of randomly segmented empty rooms to be trapped in. God save you if you hear something wandering around nearby, because it sure as hell has heard you.

They have escaped

You're a soldier recovering in a hospital, along with the few comrades that have survived. You tried to defend the city from mysterious monsters that came from nowhere, but the mission was a failure. Now your have to rest and wait for new orders.

The Backrooms as you've never seen before

Explore different levels, find easter eggs, run for your life, and have fun =) You can encounter other people, as well as strange entities all across the different levels.
