The achievement-inclusive The Da Vinci Disappearance for Assassin's Creed: Brotherhood (Xbox 360)
has been released today, available for purchase now for 800 MSP.
The DLC adds eight new single player story missions set after the fall of the Borgias, and tasks Ezio with saving the kidnapped Leonardo Da Vinci from the Hermeticists, an underground cult dedicated to "transforming mankind." Might please some of you to hear that all ten of the new achievements are tied to the content's single player portion.
It also adds more multiplayer content, the biggest expansion yet. For full details, you might want to check the DLC's announcement post
from a few weeks ago, but simply put it adds a new map, four new characters and two brand new modes: Escort, in which two teams of four have to protect their respective VIP targets while trying to assassinate another team's; and Assassinate, offering 6-8 players a simpler and recognisable deathmatch-style mode.
