In a world where shadows can possess people and influence their actions, you play as Nash, a private investigator with a rare gift: the ability to converse with shadows. As you delve into a series of bizarre disappearances in your city, you must navigate through dark secrets, unravel mind-bending puzzles, and confront your own shadowy past. Each decision influences not just the outcome of your investigation but the very essence of your own shadow, determining who, or what, you will ultimately become.
