Valkyria Chronicles (戦場のヴァルキュリア -Gallian Chronicles- Senjō no Varukyuria -Garian Kuronikuruzu-, "Valkyria of the Battlefield: Gallian Chronicles") is a tactical role-playing game developed and published by Sega for the PlayStation 3. The game was released in 2008.
The game is set in Europa, loosely based on Europe during the early years of World War II. Because of its abundance of Ragnite ore, which takes the place of petroleum in the game setting, the neutral nation of Gallia comes under attack from the East Europan Imperial Alliance, which is itself engaged in a war with the Atlantic Federation. Players take control of a unit of the Gallian Militia, dedicated to repelling the invasion. The game's visuals, which use Sega's CANVAS graphics engine, resemble a watercolor painting in motion.
Valkyria Chronicles was critically acclaimed and earned numerous awards from several notable video game publications. The success of the game spawned a media franchise, including several manga titles and an anime series. Two sequels were released for PlayStation Portable: Valkyria Chronicles II, and Valkyria Chronicles III.
