In Assassin’s Creed: Brotherhood for the PS3, Xbox 360, and PC, you can unlock the Hellequin costume for use in Multiplayer only.
To unlock the Hellequin costume, you’ll need to sign up for the Ubisoft Uplay service and access it from the main menu, then purchase the costume for 40 points. Simply playing through the game should get you enough tokens to purchase the costume.
