Assassin's Creed Odyssey developer Ubisoft has unveiled a release date for the latest installment in the series, just ahead of E3 2018. Odyssey will release October 5, 2018 on PC, PS4, and Xbox One.

Odyssey will take players to ancient Greece. Specifically, the game happens around 431 BC, in the middle of the Peloponnesian War, and prominent historical figures like the philosopher Socrates and 'Father of Medicine' Hippocrates will play a role in this adventure. You play a mercenary in the middle of the battling Athenians and Spartans but aren't on either side.
