The game is set in the same world and the same Second Europan War that provides the backdrop for the original Valkyria Chronicles and Valkyria Chronicles III.
Sega America began streaming the opening video on Wednesday for its Western release of the Valkyria Chronicles 4 game.
The continent of Europa is engulfed in the flames of the Second Europan War between the Atlantic Federation and the Autocratic Eastern Imperial Alliance.
The game will be available for PlayStation 4, Nintendo Switch, Xbox One, and PC via Steam.
