Which Assassin’s Creed game introduced the modern role-playing choice between Kassandra and Alexios?

Assassin’s Creed Odyssey introduced the role-playing choice between Kassandra and Alexios.

Released in 2018, Odyssey lets the player choose either Kassandra or Alexios as the game’s protagonist. The selected character is a mercenary descended from Leonidas I of Sparta, and the story is set during the Peloponnesian War in the fifth century BCE.

The choice affects the protagonist’s identity and voice, while the broad central storyline remains connected to the same family and historical conflict. Odyssey expands the series’ role-playing structure with dialogue choices, branching quests, multiple endings, equipment levels, and naval exploration across the Aegean world.

Kassandra is treated as the canonical protagonist in later franchise material, but the game itself permits either sibling as the player character. Bayek belongs to Origins, while Eivor is the protagonist of Valhalla. Syndicate instead centers on the twins Jacob and Evie Frye.
