Which Assassin's Creed title is set primarily in Constantinople, the capital of the Byzantine Empire?

Assassin’s Creed Revelations is set primarily in Constantinople, the Byzantine Empire’s capital. Released in 2011, it follows an older Ezio Auditore as he searches for Altaïr’s keys and investigates the Masyaf library.

The city is divided into districts influenced by Byzantine and Ottoman forces. Ezio works with local Assassins, including Yusuf Tazim, and encounters Ottoman Sultan Bayezid II’s family. Constantinople’s landmarks, such as Hagia Sophia and the Galata Tower, are integrated into traversal and missions, although the game compresses the historical city.

The title also alternates between Ezio’s Constantinople storyline, Altaïr’s memories, and Desmond’s modern-day sections. Brotherhood is centered on Rome, Rogue on the North Atlantic and New York regions, and Syndicate on Victorian London. Constantinople therefore identifies Revelations most directly.
