Which Assassin's Creed game is set primarily in ancient Egypt and features Bayek of Siwa?

Assassin's Creed Origins is set primarily in ancient Egypt and features Bayek of Siwa.

Released in 2017, Origins follows Bayek, a Medjay from the Siwa Oasis, and his wife Aya. Their personal investigation into a violent conspiracy develops into the foundation story of the Hidden Ones, the organization that later becomes the Assassin Brotherhood.

The game is set during the final period of Ptolemaic Egypt. Players visit locations including Siwa, Alexandria, Memphis, and the Giza plateau while the country is affected by the rivalry between Cleopatra and Ptolemy XIII.

Origins is not the same game as Odyssey, which is set mainly in ancient Greece, or Valhalla, which follows Eivor in the Viking Age. Its title refers to the beginnings of the Assassin tradition.
