the series. The trailer featured Lorde's cover of Everybody Wants to Rule the World, which was produced by Michael A. Levine and Lucas Cantor. The development team was able to use the new power of the PlayStation 4 and Xbox One to improve the NPC crowds. Up to 1000 individual AI characters can appear in a crowd, each acting independently and reacting to each other as well as the player's actions. The PC version of the game uses Nvidia's GameWorks technology such as TXAA anti-aliasing, advanced DX11 tessellation and Nvidia PhysX technology, due to a partnership between Ubisoft and Nvidia. Lead game designer Benjamin Plich has said this game will be more difficult than previous entries thanks to the removal of the counter button and more aggressive guards. Plich also said that the game will feature synchronized Double Assassinations. In August 2014, Assassin's Creed Rogue was announced for the PlayStation 3 and Xbox 360 and was revealed to have ties to the story in Unity. The game is written in a combination of C++ and C#, totaling an estimated 15.5 million lines of code of the former, and five million of the latter. Historical representation On October 6, 2014, Ubisoft announced that they had enlisted the help of academic historians such as Laurent Turcot, professor at Université du Québec à Trois-Rivières for daily life of 18th-century Paris, and Jean Clement Martin, a professor at the Sorbonne, to revise the script. Like other games in the series, Unity portrays a large number of real world Parisian landmarks, including the Tuileries Palace and Notre-Dame Cathedral and, through the time anomalies feature, it also includes the Eiffel Tower and the Statue of Liberty, neither of which existed at the time of the French Revolution. Notre-Dame Cathedral was modeled down to the brick, a process that took Ubisoft artist Caroline Miousse two years to complete. Because of the detail that went into the recreation of the Notre-Dame Cathedral for the game, some believe the game may help in the reconstruction of the Cathedral following the April 2019 fire that destroyed some of the building. Ubisoft donated €500,000 to the reconstruction of the cathedral and also provided Unity as a free download for the week following the event so as to give everyone a chance to explore the cathedral as they had modeled it in game. Release The game was originally intended to be released
