What is the modern-day name of Basim's Assassin's Creed game released in 2023?

Basim's 2023 game is titled Assassin's Creed Mirage.

Mirage follows Basim Ibn Ishaq before the events in which he appears as a major character in Assassin's Creed Valhalla. The game is set in ninth-century Baghdad, during the Islamic Golden Age, and traces Basim's transformation from a street thief into a Hidden One.

The Hidden Ones are the historical forerunners of the later Assassin Brotherhood. Mirage emphasizes stealth, investigations, parkour, and targeted assassinations in a more compact structure than several recent open-world entries.

The title can be confused with Valhalla because Basim is important in both games. Valhalla was released in 2020 and centers on Eivor's Viking-era story, whereas Mirage launched in 2023 and serves as Basim's own earlier adventure.
