Evil Nun: The Broken Mask is a stealth-horror game set in the world of the popular Evil Nun mobile franchise. Players must sneak through a menacing school-like environment, solving puzzles and gathering pieces of a broken mask while avoiding a relentless nun.

Stealth and evasion take priority over confrontation, as getting caught can end a run quickly. The game expands on its mobile roots with a fuller environment to explore and a deeper sense of dread built around being hunted.
