Valkyria Chronicles 4 is the fourth mainline entry in Sega's strategy RPG franchise developed for the PlayStation 4, Nintendo Switch, Xbox One and PC. The game marks the series' return to console hardware after the last two installments were created for handhelds as well as the return to the strategy genre after the franchise experimented with several spin-offs, including a mobile card game and an action title. Valkyria Chronicles 4 was initially published in Japan for the PlayStation 4 on March 21, 2018 with the Switch port and international release on other platforms to follow in the Fall of 2018.
Valkyria Chronicles 4's story takes place during the same time period as the first Valkyria Chronicles but focuses on the overarching war in Europa between the the Federation and Empire instead of just the conflict within Gallia like in past titles. The Federation, in a last ditch effect to end the long war, is attempting a risky campaign to infiltrate the Empire through the frozen north of Europa in order to invade the enemy's capital. The story follows the exploits of Commander Claude Wallace of Squad E and his childhood friends as they take part in this dangerous mission, code named "Operation Northern Cross", that will not only test their strength but the team's friendship as well.
