God of War Ragnarok is one of the most story-heavy entries in the series, bringing the Norse story arc to an end in a rather satisfying way. However, Santa Monica Studio still had some stories to tell in the Nine Realms that couldn't wait for the release of the next full-fledged entry in the series. Despite being a free expansion, God of War Ragnarok: Valhalla manages to deliver in full, providing more of what players have loved about the latest two entries in the series. God of War Ragnarok: Valhalla takes place after the main story.
