Which Assassin's Creed game introduced the playable character Jacob Frye?

Assassin's Creed Syndicate introduced the playable character Jacob Frye.

Jacob Frye is one of the two main protagonists of Assassin's Creed Syndicate, which is set in London during the Industrial Revolution. He and his twin sister, Evie Frye, arrive from Crawley and work to dismantle Templar control over the city. Jacob is generally associated with direct combat and gang leadership, while Evie emphasizes stealth, investigation, and searching for Pieces of Eden.

Syndicate was released in 2015. Its London map includes districts such as Westminster, the City of London, Lambeth, Southwark, and Whitechapel. The Fryes establish the Rooks, a gang that opposes the Blighters and supports their campaign against the Templars.

Jacob is sometimes confused with Arno Dorian, the protagonist of Assassin's Creed Unity, which immediately preceded Syndicate. Shay Cormac belongs to Rogue, while Altaïr's story is set centuries before the Frye twins' Victorian-era adventure.
