Assassins Creed Mirage is set in ninth-century Baghdad during the anarchy of Samarra, a period known for its instability from 861 to 870 during the history of the Abbasid Caliphate. The story follows Basim, a major character from Assassins Creed Valhalla, who is on a journey of self-discovery and growth as he graduates from street thief to a fully-fledged member of the Hidden Ones, the first iteration of the Assassin order founded by Aya and Bayek of AC Origins. The game was designed to celebrate the series 15th anniversary, and it was developed by Ubisoft Bordeaux, with a focus on returning to the series roots by emphasizing stealth, parkour, and assassinations over the role-playing elements featured heavily in recent installments. Assassins Creed Mirage was released on October 5, 2023, on PC, PlayStation 5, PlayStation 4, Xbox Series X/S, and Xbox One.
