About the Game
Backrooms Lost Runners is a cooperative survival-horror experience where teamwork is your only real weapon
and even your voice can put you in danger.
Trapped inside the endless corridors of the Backrooms, you and your friends must explore abandoned camps, solve environmental puzzles, manage scarce resources, and survive encounters with entities that react to sound, light, and movement. Every dark hallway hides a threat. Every whisper can give you away. Every wrong decision can separate the group forever.
Key Features
Immersive Horror Atmosphere
Venture through dimly lit corridors, abandoned shelters, and unstable spaces filled with oppressive silence, dynamic lighting, and realistic sound design. In the Backrooms, every footstep matters and every moment of silence feels wrong.

Cooperative Survival
Survival depends on communication, trust, and coordination. Share resources, split responsibilities, solve puzzles together, and make difficult choices as a team. Staying together is safer but sometimes the best loot is found far from the group.
True Cooperative Gameplay
Collaboration is crucial for survival. Manage your resources, coordinate tactics via voice chat, and make collective choices.


Voice-Reactive Threats
Face entities with different behaviors and weaknesses. Some react to sound. Some hunt through darkness. Some appear when your mind starts to break. Learn how they behave, stay quiet when needed, and use your environment to survive.

Sanity System
Darkness, fear, isolation, and supernatural events affect your mental state. Stay near light, heat sources, and safe areas to slow sanity loss. If your mind collapses, the Backrooms will begin to change around you.
Tesseract Afterlife
Death is not the end. When you die, you are pulled into a surreal Tesseract realm where you must find a way back to life. But returning may cost you time, resources, and the safety of your team.

Storyline & Quest System
Discover journals, audio recordings, floppy disks, and unsettling traces of survivors. Piece together the timeline of the catastrophe, uncover the fates of those who were here before you, and find out what is really happening inside the Backrooms.

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
Zero-gravity zones, sudden teleportation gates, shifting walls, broken physics, and impossible spaces will force you to question what is real. In the Backrooms, the environment itself can become the enemy.
YOUR ADVENTURE IS JUST BEGINNING.
