Which Assassin's Creed title was the first to let players control both Jacob and Evie Frye?

Assassin's Creed Syndicate was the first title to let players control both Jacob and Evie Frye.

Jacob and Evie are twins who share the lead role in the game's 1868 London campaign. Jacob is generally associated with direct combat and the Rooks gang, while Evie emphasizes stealth and the search for Pieces of Eden, although both can use the game's broad equipment and skill systems.

Players can switch between the siblings during much of the main story, and each has missions designed around a particular character. Some sequences require one specific twin, so the campaign is not a completely unrestricted two-character choice at every moment.

Earlier Assassin's Creed games included multiple playable figures, but they did not establish a paired sibling structure like Syndicate's. Evie is especially significant as the first woman to share top billing across an entire mainline Assassin's Creed campaign.
