In a world where every interaction creates an 'echo' of memories, you play as an 'Echo Walker,' capable of accessing the thoughts and feelings of those around you by simply speaking to them. Traveling through a futuristic city, you must navigate a series of complex relationships and unravel the mystery behind a sudden urban phenomenon causing echoes to infect people's minds. As you make choices that influence your connections, you'll face psychological challenges and moral dilemmas that shape the outcome of your journey. Each character’s unique past intertwines with your fate, and you must decide who to trust—or betray—before the echoes consume you all.
