Update 0.5 - Procedural Levels, New Entities & Major Reworks
UPDATE 0.5 IS HERE Runners, Update 0.5 is finally here. This is one of the biggest updates we have released for Backrooms Lost Runners so far. We have added entirely new systems…




Backrooms Lost Runners is a co-op survival horror with team play, voice-reactive AI, and immersive puzzles. This isn’t a “walking simulator”: explore liminal spaces, outsmart entities, and remember—even a whisper can give you away.
Backrooms Lost Runners is a cooperative survival-horror experience that challenges you and your friends to confront your deepest fears. Every environment is fraught with danger, mystery, and unexpected twists. Only through seamless teamwork and careful attention to detail can you survive and unravel the secrets of the Backrooms. 
Immersive Atmosphere
Venture through dimly lit corridors with dynamic lighting and realistic sound design. In this world, every footstep—and every whisper—could be your last.
Challenging Logic Puzzles
Engage with a variety of puzzles built around electrical circuits, switches, and ciphers. Each challenge is adapted to your team’s approach and demands inventive problem-solving.
Adaptive Threats
Face unique entities that react to sound, light, and movement. Some monsters home in on your voice; others lurk silently in the dark. Learn their behavior to stay one step ahead.
Sanity Mechanics
Monitor your mental state: staying near heat sources or in the source of light slows sanity loss.
Tesseract Afterlife
Death is just the beginning. Upon death, you find yourself in a surreal Tesseract realm where your only goal is to return to life.
True Cooperative Gameplay
Collaboration is crucial for survival. Manage your resources, coordinate tactics via voice chat, and make collective choices. 
Storyline & Quest System
Discovering scattered journals, audio logs, and flash drives you piece together the catastrophe’s timeline.
Resource Management & Character Progression
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?
Find valuable items and resources by exploring camps, lockers, and shelters.
Reality-Bending Anomalies
Beware zero-gravity zones, sudden teleportation gates, and shifting walls. In the Backrooms, the laws of physics are against you.
YOUR ADVENTURE IS JUST BEGINNING.
