The theater's acoustics hold the key to uncovering a dark mystery surrounding a vanished playwright and their never-aired final act. As Vox navigates the venue, they interact with the ghostly echoes of actors and musicians, piecing together clues through sounds that make the past come alive. Choices you make in dialogues and sound puzzles affect the storyline, the fate of the echoes, and your own life as bizarre occurrences unfold. Will you bring the echoes peace, or will you become trapped in their eerie realm forever?
