Assassin's Creed Origins is about to get its first DLC expansion. Called The Hidden Ones, it will introduce several hours of new story along with side quests, events, and items. Ubisoft has now confirmed the expansion will release on January 23 for PS4, Xbox One, and PC.

The Hidden Ones is a story-driven expansion that shares more about the growth of the Brotherhood. It takes place four years after the events of the main game in the Sinai, where players will clash with an occupying Roman force. The expansion increases the level cap to 45 and introduces two new legendary weapons, a new outfit, two new mounts, and multiple new weapons to the game. If you're a season pass owner, you can download the game at no extra cost. For others, the DLC will cost $10.
