Take up arms and defend your homeland.
Valkyria Chronicles is a game set in a fictional continent loosely based around Europe during the early stages of the Second World War. The Principality of Gallia, where our protagonists hail from, hold massive reserves of a highly flexible natural resource called Ragnite. Due to this, Gallia finds herself embroiled in the conflict between two larger superpowers, the East Europan Imperial Alliance and the Atlantic Federation.
In the game, the player assumes the role of Welkin Gunther, a lieutenant serving in the Gallian militia. Together with his trusty squad mates, you must direct them such that they win the battles they find themselves caught in, and lead them to victory for Gallia.
