Collaboration is crucial for survival. Manage your resources, coordinate tactics via voice chat, and make collective choices. Face entities with different behaviors and weaknesses. Some react to sound. Some hunt through darkness. Some appear when your mind starts to break.

If your mind collapses, the Backrooms will begin to change around you. Death is not the end. When you die, you are pulled into a surreal Tesseract realm where you must find a way back to life. But returning may cost you time, resources, and the safety of your team. Discover journals, audio recordings, floppy disks, and unsettling traces of survivors.
Piece together the timeline of the catastrophe, uncover the fates of those who were here before you, and find out what is really happening inside the Backrooms. Scavenge for food, clothing, and tools to maintain health, stamina, and sanity. Will you risk venturing alone for high-value loot, or stick close to your squad?
