The short story takes place in the middle of the events of Brotherhood as Ezio Auditore sits and gathers information about Cesare Borgia, from a hooded man who is later revealed to be Leonardo da Vinci.
The films are made by Ubisoft and have a promotional goal for the game as well as an attempt for Ubisoft to make its first step in the film industry.
