Just about every big game these days has a season pass. After all, there's a litany of content that developers usually want to add to a game during release or post release to keep players coming back for more. It's actually rare if a game doesn't have a season pass and just relies solely on the content provided out of the box if it's an AAA title. With the release for Assassin's Creed: Odyssey coming up quickly, Ubisoft is already in high-promotion mode for the open-world RPG, and just like all the other big AAA games, Assassin's Creed: Odyssey will come with a fully realized season pass.
In a press release, Ubisoft announced that there are aggressive post-launch content plans for Assassin's Creed: Odyssey, even though the game hasn't even released yet. There will be brand new episodic content released for the title, alongside free narrative-oriented content that will be available as well. The idea is to keep a "constant flow" of new content dripping into the player's feed so that they continue to stay engaged with the content long after the release of the game.
However, if you do decide to purchase the season pass, you'll instantly gain access to two bonus games, including Assassin's Creed III: Remastered and Assassin's Creed III: Liberation Remastered. Both games are the remastered editions of the six-year-old outings that originally were made available for the Xbox 360, PS3 and PC, or in the case of Liberations, the PS Vita. The games will feature all of the previously released DLC along with support for HDR and upscaled 4K output on the PS4 Pro and the Xbox One X. The remastered editions also come with higher texture resolutions and are running on the latest engine that powers the Assassin's Creed games. I do hope that the team didn't meddle too much with the actual gameplay content, as Assassin's Creed III had one of the best combat systems in a game and was thoroughly enjoyable as it was.
The remastered versions of Assassin's Creed III will be available for season pass holders starting March, 2019 next year. The rest of the live roadmap will consist of two additional story arcs, in addition to the two other Assassin's Creed titles.
The first story arc will go live in December of 2018, featuring an episodic adventure that details the first hero to unlock the ability to use the hidden blade, as well as a backstory into the formation of the Assassins and why they fight from the shadows. I don't really understand this in the context of Assassin's Creed: Origins, which already detailed why the Brotherhood was formed and why they fight from the shadows, but maybe they'll explain it more when the time comes.
The second story arc is called The Fate of Atlantis, and it will see plays confronting ancient Greek mythological gods from the deep sea, as well as uncovering the first civilization. This will be released approximately six weeks after the first story arc, and will arrive at some point in the early part of spring 2019.
