Valkyria Revolution is set in an alternate European world on the brink of war, following a group of young revolutionaries fighting for their homeland's independence. Combat blends real-time action with tactical squad commands during large-scale battles.

Players manage a special unit's abilities and equipment between missions, while the story explores themes of loyalty, sacrifice, and the human cost of war. It offers a different tone and combat style from the mainline Valkyria Chronicles games while sharing the same world.
