Built upon the new "CANVAS" engine, Valkyria Chronicles' ground-breaking 3D graphics resemble a watercolor painting in motion. Gameplay is centered around a new type of tactical battle concept. Known as "BLiTZ," this battle concept gives players unique freedom to strategically move around the environment and attack enemies using real-time controls.
