The Treacherous Valkyria (反逆のヴァルキュリア) is a downloadable content of Valkyria Chronicles 3. The DLC contains a mission called '反逆のヴァルキュリア' and can be purchased for 600Yen from the Playstation Store. It is required to finish all three pre-requisite missions (学び舎のヴァルキュリア, 街頭のヴァルキュリア, 国境のヴァルキュリア) against Aliasse, Alicia, Selvaria prior to accessing the mission against Valkyria Riela. All four Valkyrur will be in Valkyria form throughout the entirety of the mission and as such, will present a challenge to those whom wish to climb to the S-Rank. The stages used in this DLC come from previous games in the series.
