Backroom Cleaners is a 4-player co-op roguelike third-person shooter from Hypercent. Players are mercenaries hired by Axiom Corporation to suppress the Backrooms, an alternate dimension filled with grotesque Entities. The game combines squad-based shooting with roguelike upgrade choices, and each player takes on a role within the squad.

The game entered its playtest phase in late August 2026. Hypercent announced on August 18 that the playtest would begin on Steam at 13:00 JST on August 26. The test is set to run for about two weeks. The full release is planned for Q4 2026.

Game Spark's weekly indie roundup, published on August 30, highlighted Backroom Cleaners alongside two other titles: Hubert, a sheepdog adventure game, and Screw IT, a screw-sorting sim. The roundup noted the playtest was limited and gave no further release details beyond the Q4 2026 window already stated by Hypercent.
