In a bustling city where everyone wears a shadow of their true self, players navigate an underground society of shape-shifters and illusionists. As the newest recruit of an enigmatic shadow congregation, the protagonist must uncover the origins of a sinister artifact known as the Shadow Engine, which has begun to corrupt the shadows of the city's citizens, twisting them into monstrous versions of themselves. Players interact with a diverse cast of characters, make morally ambiguous decisions, and wield the power to manipulate shadows to solve puzzles and reveal hidden truths. But beware—every choice casts a new shadow.
