About the Game

Backrooms Lost Dimension is a single-player video game focused on exploring the famous and eerie levels of the Backrooms. To survive, players must solve intricate puzzles and escape malicious creatures. The game features an original, evolving story and will be constantly updated with new content through Early Access.

The Story

During an expedition, two archaeologists discover a hidden mural among ancient ruins, belonging to the mysterious Alborian civilization. Once decoded, the ancient prophecy engraved on the stone unleashes a black hole that sucks the two scholars in, plunging them into the distorted dimension of the Backrooms. Lurking in the shadows is Lady Rose, an enigmatic and iconic figure who appears to be the guardian of this place. Legend has it that if Lady Rose were to sing, her voice could collapse the entire dimension.

Backrooms: Wild Dimension (Multiplayer Mode)

Available in Q4 2026, Wild Dimension is the free-to-play multiplayer expansion of the game. Set in a distorted Backrooms timeline and structured as an open-world survival game, the action takes place on an island with diverse biomes.

This alternative reality was created by Lady Rose to deceive the Guardians of Time.

The game will operate on a Seasonal basis: each season will overhaul the island with map updates, gameplay changes, and new story fragments.
