Ubisoft has created a useful shortcut for Assassin's Creed: Odyssey players who want to access the new The Fate of Atlantis DLC without having to complete all the pre-requisites.
There are two ways to play Story Arc 2, the first episode of which is out 23rd April.
The first involves completing the main game story arc questline Between Two Worlds, and Heir of Memories, the Lost Tales of Greece questline available after completing Between Two Worlds. Then, you also have to have reached character level 28 or above.
