God of War Ragnarok brought the titular battle to life in thrilling fashion as Kratos and his allies united together in order to stop Odin and his reign. The franchise's Norse saga may have felt short-lived overall, but players got a great surprise last year that brought an all-new chapter to God of War Ragnarok. Developer Santa Monica Studio surprised many with a free DLC for Ragnarok in the form of Valhalla, a rogue-like romp through the Norse realm.
