In Assassin's Creed Odyssey, which ancient civilization's world does the player explore?

Assassin's Creed Odyssey lets players explore the world of ancient Greece.

The game is set during the Peloponnesian War, beginning in 431 BCE. Its map includes mainland Greece, the Aegean islands, and other regions connected to the Greek world. Players take the role of Kassandra or Alexios, descendants of King Leonidas I of Sparta.

The campaign combines a personal family story with the political and military struggle between Athens and Sparta. Historical figures such as Socrates, Pericles, and Alcibiades appear during the adventure, while mythical elements are incorporated into quests and locations.

Ancient Egypt belongs primarily to Assassin's Creed Origins, which takes place earlier in the Ptolemaic period. Ancient Rome is central to parts of Assassin's Creed Brotherhood and other entries, while ancient Persia is not Odyssey's principal setting. The specific historical backdrop of Odyssey is therefore classical Greece during the Peloponnesian War.
