Just like previous DLC, Update 2.0 will add a new map and game mode. The map is called "Pienza Map," a "perfect free-running playground" according to creator Ubisoft. The fresh mode is a twist on Capture the Flag called "Chest Capture," which will feature two three-man teams capturing and defending chests.
Update 2.0 will also include a "new Templar Score feature" that Ubisoft says will "reward diligent work by Abstergo recruits." I don't what that means, but hey, whatever!
Oh, and In celebration of Update 1.0's release, Ubisoft has released a trailer of the content. Check it out just below if you need to see "Advanced Alliance Mode" in action before you risk losing no money at all by downloading it and giving it a spin on either the Xbox 360 or PS3.
