Backrooms Anomaly

Backrooms Anomaly traps you in a looping corridor deep within Level 0 of the Backrooms. You inspect its yellow walls and buzzing fluorescent lights for changes, then decide whether to return to the entrance or continue through the exit. Objects may be missing or altered, the corridor may transform, and entities can appear unexpectedly.

Spot the anomalies

In Classic Mode, each correct decision builds your streak, while a mistake resets it. Reach a streak of 10 to complete a survey cycle, recover a field log and advance the investigation. Play on Normal or Hard difficulty, and use the terminal to track remaining anomalies, monitor your streak and get hints about what you missed.

The corridor uses VHS camcorder visuals and positional audio. You can adjust graphics, audio, controls and accessibility settings, including reduced camera and transition flashes, interface color-vision settings, and options to disable head bobbing, motion blur and VHS effects.

Investigate Level 0

Recover nine field logs about your assignment to catalogue the anomalies. Together, they reveal fragments of your past, who sent you to investigate Level 0, and your growing suspicions about the researchers who came before you and the hazmat-suited Warden patrolling the corridor. Discover all 70 anomalies to complete the catalogue and uncover its final entry.

Survive the corridor

Completing Classic Mode unlocks Survival Mode. Multiple anomalies can appear in each corridor; photograph them all before the timer runs out and work through the catalogue. A run ends after three missed shots, when time expires or if you are caught. After each run, review the recovered evidence and choose which photographs to preserve in your Steam screenshot library.

The catalogue includes 70 visual, audio, environmental and entity-based anomalies. The game is Steam Deck Verified and supports controllers.
