Age of Empires II: Definitive Edition's new Viking Sagas DLC introduces three civilizations—Danes, Saxons, and Varangians—with unique units and technologies, alongside a 15-scenario campaign following Harald Hardrada's rise from youth to warrior-king across Scandinavia, Constantinople, and England. The expansion includes dozens of new assets, regional units, and scenario editor tools, available now on Steam, Microsoft Store, Xbox, and PlayStation 5.
