A young boy wakes in a cave inside a vast, ruined valley, chained beside Trico, a huge wounded creature that is part bird and part mammal. Directed by Fumito Ueda (Ico, Shadow of the Colossus) and developed by genDESIGN with SIE Japan Studio, the game follows the pair as they try to escape the ancient ruins.
Play is built around exploration, climbing and environmental puzzles that the boy solves together with Trico. Trico acts with a mind of its own, so you earn its trust by feeding it, tending its wounds and directing it with simple commands, then ride and climb on it to reach new areas. Trico also protects the boy from the armoured guardians that try to carry him away.
