In a bustling metropolitan city, an underground investigation unit known as the Echo Collective has tapped into a series of strange auditory phenomena. As an aspiring sound engineer, you discover that you can not only hear the whispers of the past but also communicate with the echoes of historical figures who reveal untold secrets. Players must navigate through a web of conspiracies, solve puzzles involving sound manipulation, and make choices that influence the fate of the city, all while piecing together the mystery of your own lost voice. Will you harness the echoes to rewrite history, or will you go unheard?
