When echoes of past performers, long gone and unresolved, start to warp reality, players must navigate a web of intrigue by piecing together fragmented stories, uncovering hidden secrets, and confronting ghostly figures that threaten to rewrite history. With no clear guide, players will must explore unique environments of the theater — from the dusty stage to the haunted basement — and decipher whose echo is causing chaos, all while managing their own unraveling sanity.
