Rotten Chamber is a single-player social deduction puzzle game. The player faces a circular council of city officials, each with a unique role and identity. Some officials are corrupt and disguising themselves as honest civil servants. Through reading role-based testimony and applying logic, the player must identify and arrest the corrupt officials without wrongfully accusing the Mayor, whose arrest immediately ends the case. The game features 45 hand-designed levels across 3 acts, an endless mode, custom seeds and 15 unique roles with distinct mechanical and narrative identities.
