About
Sin Spire is a high-octane fusion of retro 90s shooter mechanics and erotic horror tension. Powered by Unreal Engine, this procedural dungeon crawler challenges players to navigate shifting, dark corridors while defending against a relentless cast of female monsters in a desperate bid for freedom.
Story
You play as a nameless wanderer trapped within the labyrinthine architecture of the Spire. With no memory of your arrival and surrounded by lustful horrors, you must ascend through procedural levels, uncovering the dark secrets of the dungeon while fighting to keep your humanity—and your life—intact.
