What to Do After Beating Assassin’s Creed Odyssey (Post-Game)
Seal Atlantis
One of the major side quests you definitely have to do in Assassin’s Creed Odyssey is the mission to seal Atlantis. After completing the main missions in Naxos, Myrinne gives you the info you need to track down the hero’s real father.
Once in Thera, Pythagoras will give you a new quest to obtain four artifacts to close the gate to Atlantis. This whole mission is tied in with the modern-day storyline as well, so this is worth doing if you want to check out all the lore in the game.
The four artifacts are tied to side quests located in Boeotia, Kythera, Messara, and Lesbos. You’ll also have to face a mythical creature for each artifact, so be prepared for some very cool and tough boss fights. We recommend hitting at least level 40 before attempting these fights, and high forties for the final artifact.
