What is the name of the Assassin's Creed game set primarily in Constantinople and starring Ezio?

Assassin's Creed: Revelations is the Assassin's Creed game set primarily in Constantinople and starring Ezio.

Released in 2011, Revelations is the concluding chapter of Ezio Auditore's main trilogy. Ezio travels to Constantinople, the capital of the Byzantine Empire, to search for keys connected to Altaïr Ibn-La'Ahad's legacy and the hidden history of the Assassin Brotherhood.

The game presents Constantinople as a major urban setting with districts, markets, rooftops, and political factions. Ezio also encounters historical figures including Suleiman the Magnificent, who is still a prince during the events of the story.

Revelations connects Ezio's narrative with Altaïr's through playable memory sequences. It is therefore distinct from Brotherhood, which centers on Ezio's campaign in Rome, and from Assassin's Creed II, which introduces him in Renaissance Italy.
