Valkyria Chronicles Key

Set on a fictional continent reminiscent of the 1930s, Valkyria Chronicles describes a Europe divided in two and ruled by two superpowers: the Empire and the Federation.
The empire set out to invade a small, neutral country called Gallia, located in the middle of the territories of the two superpowers, in an attempt to secure invaluable natural resources.
In this battle, a hero named Welkin and his comrades from the 7th platoon of the Federation, fight against the invasion and attempts of the Empire to unify the continent under his power.
