The Notre Dame cathedral, a historic landmark located in Paris, took one developer two years to create in Ubisoft's Assassin's Creed Unity, Destructoid reports.
Assassin's Creed Unity takes place during the French Revolution. The giant cathedral in-game is the work of senior level artist Caroline Miousse, who worked with a historian to research and build every section.
"I was pleased to do that," Miousse said. "It was very exciting, but there was a little stress at the beginning because you really need to be sure that you're recreating it as accurately as possible because it's so well known."
The goal was to faithfully recreate the cathedral in a 1:1 ratio. However, the artwork inside the Notre Dame — including its stained-glass windows — will differ slightly due to copyright laws.
Assassin's Creed Unity launches Nov. 11 for PlayStation 4, Windows PC and Xbox One. Reports suggest that the game will run at 900p and a frame rate of 30 frames per second on PlayStation 4 and Xbox One.
