Backrooms: Code Yellow

Backrooms: Code Yellow is an online cooperative game that supports between one and six players. It is set in a very large and unpredictable realm made up of endless rooms, hallways and distorted architecture. The game is based on the Backrooms concept and casts players as explorers entering this space.

Players work together to explore the environment, complete tasks and collect data. After gathering what they can, they return to earn funding for the next day’s work, which gives the game a repeating cycle of expeditions. The game description also notes that players may not be alone in the realm, suggesting other presences are located within it.

The game can be played solo or in groups, with co-op play handled online. The structure centres on cooperation, exploration and returning from each trip with results that support further runs.
