"Assassin's Creed 2 DLC 2 "Bonfire of Vanities" will release on February 18 on PS Store and Xbox Live" said a Ubisoft representative.
In this DLC your task is to free Florence from the evil Monk Savonarola, with the help of Machiavelli. It contains ten memories that open up the area of Florence that was unavailable in the main campaign. You'll also get a new spring-jump move for Ezio.
The first screenshots have been released here.
