Valkyria Chronicles, known in Japan as Battlefield Valkyria: Gallian Chronicles (戦場のヴァルキュリア -Gallian Chronicles-, Senjō no Varukyuria -Gallian Chronicles-?), is a tactical role-playing game published by Sega exclusively for the PlayStation 3 and was developed by Sega WOW's Overworks division. It was released in Japan on April 24, 2008. A European version was then released on October 31, 2008 before a North American version was released on November 4, 2008.
The game is set in Europa, a fictional version of Europe, in 1935. Because of its abundance of ragnite ore, which can be refined into a powerful fuel, 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 an uprising of Gallian nationals, dedicated to repelling the invasion. The game's visuals, which feature SEGA's CANVAS graphics engine, have received a lot of attention - with CANVAS, the game's entire graphical style is built to resemble a watercolor painting in motion.
In the year 1935 EC, the continent of Europa was dominated by two super powers: The Autocratic East Europan Imperial Alliance on the east and a commonwealth of loosely allied democracies known as the Atlantic Federation on the west. The economy of both powers depended on the precious multi-purpose mineral of Ragnite. Its growing scarcity resulted in the Empire aggressively invading the Federation's eastern border, sparking the Second Europan War. The Empire, with its military superiority quickly put the Federation on the defensive. Emboldened by their progress and momentum, the Empire decided to start a second front and invaded the neutral nation of the Principality of Gallia on its western border.
When Imperial forces launch an attack on the Gallian border town of Bruhl, Welkin Gunther, son of late General Belgen Gunther, was forced to fight for his life alongside Town Watch captain Alicia Melchiott. Along with Welkin's adopted sister Isara, the three escaped to Gallia's capital of Randgriz and subsequently joined the country's militia forces. Welkin was given the rank of lieutenant and was assigned as the commander of the newly-formed militia Squad 7 with Alicia acting as his non-commissioned officer. Initially members of the squad questioned Welkin's qualifications to be a commander due lack of combat experience. However, he quickly earns their trust and loyalty with his tactical genius. Together they fight in order to drive the Imperial forces out of Gallia, as well as discover the true purpose of the invasion itself.
