Which Assassin's Creed game takes place mainly in Ptolemaic Egypt?

Assassin's Creed Origins is the Assassin's Creed game that takes place mainly in Ptolemaic Egypt.

Released in 2017, Origins follows Bayek of Siwa, a Medjay who becomes involved in events surrounding Cleopatra, Julius Caesar, and the formation of the Hidden Ones. The game explores Egypt during the first century BCE, when the Ptolemaic Kingdom was moving toward Roman domination.

Origins is important to the franchise's chronology because it depicts the beginnings of the organization that later becomes known as the Assassin Brotherhood. It also introduced a more role-playing-focused structure, including experience levels, equipment rarity, and a large map with quests.

The game's setting is sometimes confused with Odyssey, which is primarily set in Classical Greece, or Mirage, which is set in ninth-century Baghdad. Origins is specifically associated with ancient Egypt and Bayek's home of Siwa.
