Which game is the first Assassin's Creed title to feature Basim as its main playable character?

Assassin's Creed Mirage is the first Assassin's Creed title to feature Basim as its main playable character.

Released in 2023, Mirage follows Basim Ibn Ishaq in ninth-century Baghdad. The story shows his transformation from a street thief into a Hidden One under the guidance of Roshan, an experienced mentor.

Mirage is set before the main events of Assassin's Creed Valhalla, where Basim is an important supporting character. Its Baghdad setting and stealth-focused design deliberately recall several features of earlier Assassin's Creed games, including a dense city, social stealth, and contract-based assassinations.

Basim should not be confused with Eivor, the protagonist of Valhalla, or Altaïr, the protagonist of the original game. Mirage explores Basim's earlier life and the mystery surrounding his identity.
