The Assassin’s Creed franchise has always been a mixture of three different stories. There’s the present day narrative, the historical Assassins vs. Templars story, and also the tale of Those Who Came Before–the Isu–and the creation of their Pieces of Eden. Prior to Assassin’s Creed Odyssey, the franchise wove together these three narratives into one playable story across each of its games, but Ubisoft’s newest title splits its campaign into three separate parts.
As a result, beating Assassin’s Creed Odyssey’s main campaign–Kassandra or Alexios’ story–and watching the last cutscene is not the end. Kassandra and Alexios’ quest does conclude, but the ending to both the present day narrative and the Isu story can only be unlocked by completing certain optional quests. In total, there are three “final” cutscenes in Assassin’s Creed Odyssey, and the optional two are fairly easy to miss. Read ahead to make sure you don’t.
The rest of this article delves into several of Assassin’s Creed Odyssey’s mid- to late-game features and missions. If you haven’t at least finished Episode 7 of the game–you’d have unlocked the “Legend in the Making” Achievement/Trophy–then turn back if you don’t want to be spoiled. If you’re at least at that point, don’t worry. We won’t be going into detail about what Odyssey’s three endings are or the serious lore implications some of them have. This is just a guide for how to reach those endings.
First Storyline – Odyssey
This is the first storyline you unlock in the game, and probably the first you’ll complete. The game’s main story–as it primarily focuses on Kassandra and Alexios’ quest to reunite their family–is called Odyssey, and it’s the only mandatory narrative you need to complete to beat Assassin’s Creed Odyssey. Doing so will cause the game’s credits to roll.
The Odyssey storyline can end in several different ways depending on your actions throughout the game. Who you saved, which targets you killed, and what dialogue options you picked determine one of nine different conclusions to Kassandra and Alexios’ story. However, if you want to know what happens to some of the other characters–both during ancient Greece and in the present day–as well as how Assassin’s Creed Odyssey ties into the rest of the franchise, you’ll need to finish the two optional stories.
Second Storyline – Hunt The Cult Of Kosmos
You’ll discover the Cult of Kosmos relatively early into Odyssey’s storyline, and from there it breaks off into a separate questline called Hunt The Cult Of Kosmos. Snippets of this storyline will interweave into Odyssey throughout the rest of the game, but to complete Hunt The Cult of Kosmos, you’ll need to do a lot of optional assassination missions.
Completing Hunt The Cult Of Kosmos unlocks an extra cutscene that completes the present day narrative. Layla and her companions’ story is left fairly open at the end of the game, so if you want to see what happens next, you’ll have to finish Hunt The Cult Of Kosmos. To do that, you’ll need to kill the leader of the cult, who’s known as The Ghost of Kosmos.
Getting to The Ghost is not nearly as straightforward as the game’s other targets. There are eight branches of cultists, seven of which have six members while the last only has one. You’ll need to follow clues to discover the identities of every low-ranking member, find each one, and kill them; that’s the only way to learn the identities of the Sages they serve. Each of the eight Sages hides a clue to The Ghost’s identity, so once you’ve dealt with them, you can go after the cult’s mastermind.
You will need to be a high level–somewhere between 48 and 50–and carry very good armor and weapons to deal with some of the cult’s strongest members. Because of how long Hunt The Cult Of Kosmos is, there’s a good chance you complete the other two storylines first, but the order doesn’t matter. Some of the cult’s members are relatively weak–between levels 15 and 20–so you can start hunting for their identities while completing the other two storylines and return later to kill any high ranking cultists after Kassandra/Alexios has grown stronger.
Third Storyline – Between Two Worlds
The final cutscene is unlocked by completing the third narrative, Between Two Worlds, which only becomes available once you discover the lost city of Atlantis during the Odyssey storyline. Between Two Worlds is the shortest storyline in Assassin’s Creed Odyssey, but it’s arguably the hardest.
To complete it, you’ll need to overcome four mythological creatures in the world. Three of them–the Minotaur, the Cyclops, and Medusa–are some of the game’s hardest boss battles. The fourth, the Sphinx, is a series of challenging riddles. You’ll start Between Two Worlds about three-quarters of the way through Odyssey, but you’ll probably still need to level up a bit before taking this storyline on.
You definitely want to complete Between Two Worlds, though. The four mythological creatures represent some of the most fascinating side quests, amazing fights, and clever puzzles in the entire game. Plus, the cutscene you earn for completing the storyline provides both answers and further questions to the Isu, the Pieces of Eden, and what might be included in Assassin’s Creed Odyssey’s upcoming The Fate of Atlantis DLC.
