This game uses Unreal Engine 5; avoid running on outdated hardware.

(Some VR headsets might have compatibility issues. I don't own all of the headsets yet to test with.)
Currently Tested Headsets:
• Oculus Rift
• Meta Quest 2

////If you are using the Quest you should go into your Oculus app and change your OpenXR settings to the Oculus one. Unreal Engine did a bug in the new game engine update and now you have to change that setting or it glitches the headset display.////

If you're not careful and you noclip out of reality in the wrong areas, you'll end up in the Backrooms. The old moist carpet, the mono-yellow rooms and the hum-buzz of the fluorescent lights will be your only comfort in the endless purgatory you have found yourself in. Don't bother crying out for help. Nobody is coming. Nobody is left.

Level 0 (The Lobby)
Level 0 is the first level of the Backrooms.
Level 0 is a non-linear space, resembling the backrooms of a retail outlet. It is a collection of infinite randomly segmented rooms, hallways, and staircases. The wallpaper is a mono-yellow, the carpet is damp, and the ceiling is decorated with office lights. Some walls have electrical outlets, security cameras, or mold growing on them.
The installed lighting flickers inconsistently and hums at a constant frequency.
While most areas of Level 0 are lit with a mono-yellow light, some areas are in total darkness. Other areas have dimmer than usual lights and some areas even have colorful lighting.
