We all know by now that the release of a big-budget game is not the end of the story. Today's case in point is Assassin's Creed: Origins, which has Ubisoft announced will have a season pass with two expansions, plus a pair of cosmetic packs, 500 Helix Credits, and an "exclusive rare weapon" called the Calamity Blade. And for those of you who don't want to pony up for the extras, there's some free stuff on the way too. 

The first expansion, The Hidden Ones, will take place years after the events of Origins, and "builds upon the growth of the Brotherhood" as it comes into conflict with Roman occupiers in another part of Egypt. Following that will be The Curse of the Pharaohs, in which "players will fight against undead Pharaohs and explore a new, mystical realm." Hidden Ones is expected to be out in January 2018, while Curse of the Pharaohs is slated for March; both expansions will increase the level cap of the base game, and Curse of the Pharaohs will also add new abilities to the mix.
