Backrooms: Lost Signal

Early access
Achievements

Backrooms: Lost Signal is a cooperative horror experience where survival is never guaranteed. Trapped in endless, unfamiliar spaces, you must explore, communicate, and make decisions that will define whether you live or die.

Play alone or team up with up to four players as you explore the Backrooms together. Staying together may keep you safe in some cases, but splitting up might be the only way forward. Every choice you make as a group can mean survival or disaster.

Puzzles are integrated directly into the environment, forcing you to pay attention while dangers are present. There is rarely time to feel safe, and every solved puzzle pushes you deeper into the unknown.
