Following up the release of Hunted, this is now the second story-pack to expand the story of Odyssey and connect it to the larger, overarching plot of the series.
If you’re slightly confused about the structure, allow me to explain. Assassin’s Creed Odyssey, in addition to various miscellaneous pieces of content like item and customization packs, will have 2 big story DLCs, Legacy of the Hidden Blade and the Fate of Atlantis. Each of those DLCs are separated into story-arcs which will give you new quests and rewards.
They are separated in time as to provide suspense for those heavily invested into greater story of Assassin’s Creed. The first story-pack, released on December 4th introduced us to the philosopher-assassin-idealist, the first person to ever use the hidden blade against the autocrats of all stripes who would later become the Templar Order.
This is a way to connect the protagonist of Assassin’s Creed: Odyssey (who is canonically Kassandra) to the complex world of the shadow war between the two organizations and provide those crucial, narrative steps in turning them from a mercenary into an assassin. The story by its nature is more linear than the overall Odyssey experiences, providing less of a wiggle room for big, important choices
and the DLCs are, of course, en tirely optional and serve only to provide context.
The second part of the DLC, the Shadow Heritage, serves to explain how the illustrious lineage of Assassins that continues to this day got started. Without going into spoiler territory, it involves intrigue, possibly tough decisions and romance. Bloodline will, presumably, conclude this story with an introduction to the next generation of Assassins in a sort of “passing down the torch” moment (the fact that the setting is Ancient Greece and that’s some heavy Olympics parallel are probably intentional).
The next big DLC, the Fate of Atlantis, will veer into a completely unexplored territory, introducing mythical creatures to the world of Assassin’s Creed and presenting the story of the fabled city of Atlantis (the mythical one, not the actual one described by Plato). With the amount of additional content available, you’ll likely be able to enjoy Assassin’s Creed: Odyssey for the bigger portion of the year.
