Starting in the African front of WWII, the Wolf Pack, a squad of supernatural soldiers fighting for the Allies, must undertake a series of dangerous missions to retake Africa and take the fight to Berlin. Standing in their way are Nazis, zombie Nazis, vampire Nazis, and more.
Operation Darkness is a tactical role-playing game. Move units, have them attack, or use special abilities. Also available in this game are cover tactics, which allow for combined attacks, covering fire, and faster movement. Between missions, supplies can be purchased and equipped, skills can be swapped out, and new missions can be selected. Story missions cannot be replayed, but optional replayable non-story missions exist to give extra experience and equipment.
Online missions exist, where up to four players, each bringing up to three units from the campaign, can fight the Axis powers together. Experience and gear earned in this mode is not kept, but victories unlock new gear to purchase between missions.
