Assassin's Creed Mirage is a 2023 action-adventure game developed by Ubisoft Bordeaux and published by Ubisoft. The game is the thirteenth major installment in the Assassin's Creed series and the successor to 2020's Assassin's Creed Valhalla. While its historical timeframe precedes that of Valhalla, its modern-day framing story succeeds Valhalla's own. Set in 9th-century Baghdad during the Islamic Golden Age—in particular during the Anarchy at Samarra—the story follows Basim Ibn Ishaq (a character first introduced in Valhalla), a street thief who joins the Hidden Ones to fight for peace and liberty, against the Order of the Ancients,[b] who desire peace through control. The main narrative focuses on Basim's internal struggle between his duties as a Hidden One and his desire to uncover his mysterious past.
