Assassin’s Creed Origins’ season pass will include two story-driven expansions that will be released in 2018, including one that will let players — as protagonist Bayek — battle mythical Egyptian beasts. A piece of free downloadable content will go a little bigger, letting you fight the Egyptian gods themselves.

The game’s season pass, which is available as part of Assassin’s Creed Origins’ $99.99 Gold Edition and will be sold separately, includes some cosmetic goods and in-game currency in addition to its story-driven DLC.
