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.

This game uses Unreal Engine 5; avoid running on outdated hardware.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