Rotten Basement

A horror-themed adult game set in a decaying mansion. The player takes on the role of a newly hired maid tasked with cleaning a long-sealed basement that harbors grotesque monsters—tentacle creatures, worms, and malevolent spirits. As the maid and her colleagues descend into the filthy depths, they suffer injuries and damage that visibly alter their appearance. The game combines survival horror mechanics with resource management: players must use first-aid items to treat injuries as they progress. As some monsters escape the basement, the horror spreads throughout the mansion itself, transforming the once-quiet estate into a labyrinth of danger. The player is joined by a professional pest exterminator and a practitioner of occult magic to contain the threat. A secret "Master Mode" allows the player to experience the story from the mansion owner's perspective, aware of hidden truths from the start.
