About Backrooms bacteria: Escape the Bacteria in 60 Seconds

Backrooms bacteria drops players into a tense multiplayer escape scenario where the goal is simple and urgent: get away from the bacteria before it reaches you. The game takes place in the unsettling interior spaces of the backrooms, and the 60-second countdown before the bacteria begins attacking gives every session an immediate sense of pressure.

Several scenes show yellow patterned wallpaper covering rectangular interior pillars and walls beneath a flat grey ceiling fitted with recessed white light panels. In one scene, a tall, spindly black figure with wire-like limbs stands in the center of an open hallway. Several scenes also show a character wearing a bright yellow hooded suit with a black gas mask and a black biohazard symbol on the back.

How to Play Backrooms bacteria

Click the game button to begin. Once inside, you are taken backstage and given 60 seconds to run away or find a hiding spot. The bacteria selects its target randomly, so no player is guaranteed safety. Communication with other players is part of the experience as everyone works to escape.
