In a world where sound holds the key to hidden truths, players assume the role of Echo, a person trapped in a haunting echo chamber that reflects the past and present of those who once entered. Armed with the power to manipulate sound and project conversations, players must navigate through eerie hallways while unveiling the forgotten stories of long-lost souls. Each echo provides clues to unlock chambers and solve puzzles, revealing not just the identities of the past occupants, but uncovering a deeper mystery that threatens to break the fabric of reality itself. The atmospherics will challenge players' perception—a balance of fear, intrigue, and intellect as they piece together the truth of their own existence.
