Echo

ECHO is a third-person science-fiction adventure about En, a girl who arrives at a legendary Palace after a century in stasis. She hopes to use forgotten technology to bring back a life that should not have been lost, but the Palace’s ancient halls hold dangers she could not anticipate. As En descends, the story explores her past and connection to the Palace, the man she wants to revive, and the circumstances of his death.

The Palace and its copies

The Palace studies En and creates Echoes: exact copies of her that behave as she does. They learn from her actions and use them against her. Sprinting teaches them to move faster, sneaking makes them stealthier, and shooting teaches them to shoot back, so the way you play shapes the enemies you face.

Stealth and action

Gameplay combines stealth, action and the use of the Palace’s technologies. The Palace periodically reboots, causing a blackout that updates the Echoes with En’s latest behavior. During the blackout, the Palace is blind and En can act without teaching the Echoes; she can use this time to run and shoot without those actions being learned. Each cycle pits her against the choices she made during the previous one, allowing you to influence how the Echoes behave while adapting to survive.
