Tales of Zestiria (Japanese: テイルズ オブ ゼスティリア, Hepburn: Teiruzu Obu Zesutiria) is a Japanese role-playing game. It is the fifteenth main entry in the Tales series, developed by Bandai Namco Studios and published by Bandai Namco Entertainment. It was released in January 2015 in Japan on the PlayStation 3. For Western release in October of the same year, it was also ported to PlayStation 4 and Microsoft Windows via Steam. The PS4 version was released in Japan in July 2016. As with previous entries in the Tales series, the game uses a variation of the action-based Linear Motion Battle System, with additional elements including a navigable open world, and the ability for certain characters to fuse into a single entity in battle to deliver powerful attacks.
The story follows Sorey, a young man blessed with powers by a mystical spirit race known as the Seraphim who act as a stabilizing force in the land, as he travels to free the land of Glenwood from the threat of the Hellion, creatures spawned by negative emotions. The game's characteristic genre name is Jōnetsu ga sekai o terasu ārupījī (情熱が世界を照らすRPG, lit. "RPG of Passion Lighting the World"), with its story focusing on the passion of the characters.
