THE BACKROOMS
The Backrooms, based off the Found Footage short film by Kane Pixels! This is an improved Backrooms map, sticking closely to the original concept with various elements from Kane Pixels' lore. This map is a fairly large rendition of the Backrooms concept, with nothing but repeating walls, painful amounts of mono-yellow, the classic fluorescent light hum, and an inescapable sense of loneliness.
Credit to the amazing schlimbo for many of the custom models in the map; their own Backrooms map can be found here.
This addon also includes a second map, gm_backrooms_classic, with all ASYNC-related things removed, plus a doubled map size. It is intended for people that prefer the original look of the Backrooms without all the new lore.
"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."

[hr][/hr] Recommended addons:
- Carpet Footsteps so the carpet actually sounds like carpet
- Cinematic Camera for immersion and realism
- Advanced Material for texture customization across the map (alternate Backrooms textures are provided above the threshold)
- There is also an alternative nodegraph you can use for more accurate NPC navigation
If you encounter any bugs or issues with the map, feel free to let me know in the comments. Please contact me if you wish to port, redistribute, or modify my work in any way.
