Set in a dystopian city where technology has advanced to the point of creating emotional echoes—projections of a person’s feelings and memories that can manifest in the real world—players take on the role of a retired investigator whose echo has gone rogue. As they navigate a labyrinth of urban nightmares filled with both allies and potential enemies, they must untangle the web of echoes that haunt the city, risking their own sanity along the way. Each interaction reveals new layers of mystery as echoes can help or hinder the investigation, forcing players to confront their own buried memories that have come back to 'haunt' them.
