Assassin’s Creed Odyssey is an action role-playing video game developed by Ubisoft Quebec and published by Ubisoft, released in 2018 for platforms including Xbox One, PlayStation 4, and PC. Set in ancient Greece during the Peloponnesian War (431–422 BCE), it follows the player’s chosen protagonist—either Kassandra or Alexios—a mercenary navigating a richly detailed open world. The game blends historical fiction with mythology, featuring real-world locations like Athens and Sparta alongside mythical elements like the Minotaur.
Players engage in exploration, combat, and dialogue-driven quests, with choices impacting the story’s outcome, a first for the series. The narrative centers on uncovering the protagonist’s family history and confronting the Cult of Kosmos, a secretive group manipulating the war, while interacting with historical figures like Socrates and Pericles. The game introduces RPG mechanics, including skill trees, gear customization, and romance options, enhancing player agency.
