Backrooms: Threshold

The Backrooms have been breached.

An experimental gateway has opened a path into the Backrooms, an endlessly generated labyrinth of impossible architecture.

Enter alone or with your team to map unexplored spaces, document unexplained phenomena, recover anomalous objects, and investigate entities that should not exist.

Every expedition takes you somewhere different. Familiar corridors can give way to vast chambers, split levels, sunken spaces, bridges, overlooks, and strange structures formed by the procedural architecture itself.

You never know what lies beyond the next wall. (or beneath it)

Explore a Procedurally Generated Backrooms

The architecture itself is generated.

Every expedition begins with a randomized seed, creating a new world from the ground up. Not from prebuilt rooms, but from procedurally generated spaces, connections, elevations, and structures.

With over 4 billion possible seeds, each generating an effectively infinite world, every portal can open somewhere entirely different. From the moment you step through, you can encounter spaces and structures that no other player has ever seen before.

Familiar corridors can open into vast chambers, split across multiple levels, or continue into strange spaces above and below you.

Every expedition is a journey into a Backrooms that may have never existed before.

Investigate the Unknown

Every expedition is an opportunity to discover something new.

Bring specialized research equipment into the Backrooms to document entities, uncover hidden anomalies, and gather evidence of the unexplained.

• Capture entities and strange phenomena with your camcorder.

• Photograph anomalous objects and environments.

• Use specialized instruments to detect what can't be seen.

• Map the world around you as you explore.

• Return with evidence, samples, and discoveries to advance your research.

Not everything you discover can be brought back. Sometimes, the evidence is all you'll have.
