Battle of Forlì is the first of two DLC extensions planned for Assassin's Creed II. It comprises the first of the two "corrupted memories" of the Animus (DNA sequence 12), and sees Niccolò Machiavelli and Caterina Sforza fighting alongside Ezio to protect a piece of Eden from the Orsi brothers and the Templars. Battle of Forlì contains six new missions, in which Ezio will use Da Vinci's flying machine once again. As the title suggests, this first DLC package takes place in the region of Forlì.
