Which Assassin's Creed game follows Shay Cormac after he joins the Templars?

Assassin's Creed Rogue follows Shay Cormac after he joins the Templars.

Shay Patrick Cormac begins the game as an Assassin operating in the North Atlantic during the Seven Years' War. After a disastrous mission and a deep disagreement with the Assassin leadership, he turns against the Brotherhood and becomes a Templar. The game therefore presents the conflict largely from a former Assassin's perspective.

Rogue includes locations in the North Atlantic, the Appalachian frontier, and New York City. Shay commands the Morrigan, a fast ship adapted for icy waters, and the campaign includes naval exploration, hunting, and combat. Its story overlaps chronologically with events from Assassin's Creed III, Black Flag, and Unity.

The title is sometimes confused with Unity because both were released in 2014 and their narratives intersect near the French Revolution. Rogue, however, is specifically the game centered on Shay's defection and his service to the Templars. It was initially released for PlayStation 3 and Xbox 360.
