Which Assassin's Creed game centers on Bayek of Siwa?

Assassin's Creed Origins centers on Bayek of Siwa.

Bayek is a Medjay, an elite protector and lawkeeper in ancient Egypt. The game follows his investigation into the forces responsible for a personal tragedy and shows how his experiences help shape the early Hidden Ones, the organization that later becomes the Assassin Brotherhood.

Origins was released in 2017 and is set primarily during the first century BCE, amid the political struggle involving Cleopatra, Ptolemy XIII, and Julius Caesar. Its open world includes locations such as Alexandria, Memphis, and the Egyptian desert.

The title is often confused with Odyssey because both games depict the ancient Mediterranean. Odyssey follows Kassandra or Alexios in fifth-century BCE Greece, while Origins follows Bayek in Ptolemaic Egypt. Origins also introduced a stronger role-playing structure to the main series.
