The plot is set in a fictional history of real world events and follows the centuries-old struggle between the Assassins, who fight for peace with free will, and the Templars, who desire peace through control. The story is set in Paris during the French Revolution; the single-player story follows Arno Victor Dorian in his efforts to expose the true powers behind the Revolution. The game retains the series' third-person open world exploration as well as introducing a revamped combat, parkour and stealth system. The game also introduces cooperative multiplayer to the Assassin's Creed series, letting up to four players engage in narrative-driven missions and explore the open world map.
