Great sci-fi usually begins without explaining itself to the audience. In ECHO, you play as En, a ‘Resourceful’ in search of a legendary, possibly fictional palace. Events have already transpired, and En is desperate. You are not meant to immediately. But you’ll want too.

Like other great cold openings in sci-fi, you feel instantly drawn into the world, curious about what each term means and how the world differs from our own. Through conversations between En and her reluctant partner London, the world and our central cast slowly reveals itself to the player.
