Valkyria Chronicles is a tactical role-playing game developed and published by Sega for the PlayStation 3 in 2008. A Microsoft Windows version was released on November 11, 2014. A remastered version for PlayStation 4 was released in Japan on February 10, 2016 with a Western release planned for May 2016. Both PC and PS4 versions include previously released DLC. The game is set in fictional 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 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 pencil drawn paintings in motion.
