Assassin's Creed Mirage is a massive game despite its main story only lasting around 20 hours. While the wilderness outside Baghdad is a sprawling open world full of plenty of secrets to find and a few smaller villages to explore, the city itself is divided into four regions and can take players hours to traverse it all. One of those regions is the Karkh region, which, although it is larger than the others, contains fewer collectibles than the Abbasiyah and Harbiyah regions.
