Which Assassin's Creed game follows Bayek of Siwa as its main protagonist?

Assassin's Creed Origins follows Bayek of Siwa as its main protagonist.

Bayek is a Medjay, a protector and law officer from the Egyptian settlement of Siwa. The game follows his investigation into a conspiracy that affects his family and eventually connects to the origins of the Hidden Ones, the organization that later develops into the Assassin Brotherhood.

Assassin's Creed Origins was released in 2017 and is set in Ptolemaic Egypt during the first century BCE. Major locations include Alexandria, Memphis, Cyrene, and the Great Sphinx area. The game also depicts Cleopatra VII and Julius Caesar as historical figures within its fictional narrative.

Origins changed the series by adding stronger role-playing systems, including levels, equipment rarity, quests, and a large open world. It is distinct from Odyssey, which follows Kassandra or Alexios, and Valhalla, which follows Eivor. Bayek is also associated with Aya, his wife and an important founder of the Hidden Ones.
