Assassin’s Creed Mirage will include an interactive history feature available in the game at launch, allowing you to delve deeper into the real world version of the game’s Baghdad setting.
This option appears to be an alternative to the more involved Discovery Tour mode that popped up some time post-launch in Assassin’s Creed Origins, Odyssey and Valhalla. Perhaps befitting Mirage’s more condensed nature, this option too sounds less involved.
Appropriately titled the “History of Baghdad”, the option is described as being similar to the series’ traditional Codex, and has been built in partnership with a series of museums and international historical institutions.
