Assassin's Creed Unity is an action-adventure video game developed by Ubisoft Montreal and published by Ubisoft. It was released in November 2014 for Microsoft Windows, PlayStation 4 and Xbox One. The game was released for Stadia in December 2020. It is the eighth major installment in the Assassin's Creed series, and the successor to 2013's Assassin's Creed IV: Black Flag. It also has ties to Assassin's Creed Rogue which was released for the previous generation consoles, the PlayStation 3 and Xbox 360 on the same date. 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. Assassin's Creed Unity received mixed reviews. It was praised for its visuals, customization options, setting, and characterization. Critics were more polarized on its narrative, mission design, multiplayer-oriented format, and gameplay, with the latter in particular complimented for its improvements, but criticized for a lack of innovation and for feeling unrefined. The game was panned for its numerous graphical issues and bugs upon release. Because of the game's poor launch owing to the technical issues, Ubisoft issued an apology, and offered compensation. Assassin's Creed Unity was followed by Assassin's Creed Syndicate, which takes place in Victorian London, and was released in October 2015.
