In God of War: The Card Game, players take on the role of the Norns, powerful individuals from mythology, as they try different combinations of heroes and Quests in order to stop Ragnarök. Each Quest is made up of a mosaic of cards, representing the foe that the Norns must fight against. By building up their own special combat deck of cards, the Norns will gain power as they battle along. If they can defeat all three Quests set before them, then Ragnarök can be stopped.
