After Kotaku reported that the next Assassin's Creed game would be called Assassin's Creed Odyssey and was set in Ancient Greece, Ubisoft has now officially announced it Thursday. Via this short GIF and a "this is Sparta" boot.
That's all Ubisoft is showing for now. We'll likely see a lot more at E3.
