Two videos in a making-of Assassin's Creed Unity series have been released.
The first IGN episode covers the creation of the upcoming PS4, Xbox One and PC title from a technical standpoint, highlighting aspects such as the game engine, the split of workloads between various Ubisoft studios and how the E3 2014 demo was created.
The second episode focuses on how Ubisoft leveraged the power of Xbox One and PS4 to create a next-gen Assassin's Creed game.
Assassin's Creed Unity is set in 18th century Paris, during the French revolution, with players cast as French-Austrian assassin Arno Victor Dorian.
Ubisoft has said the game features its "biggest playground ever", which has been "filled with hundreds of quests, activities and rewards".
The Assassin's Creed Unity release date is set for October 28 on PC, PS4 and Xbox One.
