Assassin's Creed Odyssey: The Family Odyssey (Chapters 1–9)

Fri, 11 Sep 2026 13:05:00 +0000

This is Part 1 of the canonical playthrough . Finish these nine chapters before Legacy of the First Blade. You can hunt Cultists and side quests in the same regions as you go. Do not start Korfu.

Kassandra is the canon protagonist. The family members swap names if you play as Alexios (you are then hunting Kassandra as Deimos). The choices below are the same either way.

The family arc is one of three base-game stories. Completing Chapter 9 does not end the game. It ends the bloodline plot and unlocks the Sparta dinner if you kept everyone alive.

Assassin's Creed Odyssey: Hunting the Cult of Kosmos

Fri, 11 Sep 2026 13:06:00 +0000

This is Part 2 of the canonical playthrough . Start it the moment The Serpent’s Lair in Phokis unlocks the Cultists menu. Finish it after the family dinner , not before Deimos is resolved.

How the board is built

The Cult of Kosmos in 431–422 BCE is 44 people:

42 regulars in seven branches (five adepts + one Sage each).
Deimos, the Cult’s champion, sitting outside the seven. You cannot clue-hunt Deimos to death. The family story decides that fate on Mount Taygetos.
The Ghost of Kosmos, the leader. Every Sage drops a clue toward the Ghost. You unmask them only after the seven Sages are gone and Deimos is resolved, then play A Fresh Start.

Killing the five adepts in a branch identifies the Sage. Killing a Sage yields a legendary set piece, a Ghost clue, and usually a fat XP spike. That is why this pillar should run in parallel with the chapters: many adepts live in regions the family story already sends you through.

Assassin's Creed Odyssey: Mythical Beasts and the Gates of Atlantis

Fri, 11 Sep 2026 13:07:00 +0000

This is Part 3 of the canonical playthrough . It is the third base-game pillar — the Isu / First Civilization thread — and the mandatory prologue to Fate of Atlantis .

How Atlantis actually unlocks

You cannot sail to a map pin called Atlantis on day one.

Reach Chapter 6 of the family arc and finish United Front on Naxos.
Play A Family’s Legacy. It sends you to Thera (the volcanic island marked as the Caldera of Fate).
Redirect the light beam into the sealed door, go inside, and meet Pythagoras — your blood father, not Nikolaos.
That starts the Between Two Worlds line and the quest The Gates of Atlantis. Pythagoras will not seal the city until you bring four Precursor artifacts.

Those artifacts sit on four mythical “gods” the Greek world has been telling stories about. Each is a full quest chain, not a single arena fight. Recommended level is the high 40s to 50. Do the family ending first if you are underleveled; the beasts will wait.
