We've got a brand new Developer Diary from Ubisoft Montreal for the upcoming Assassin's Creed Brotherhood. In this one, we get a little bit more back story about what Desmond will be doing on the 2012 side of things, as well as a heavy focus on some of the new Multiplayer aspects in the game. We see some of the new character leveling and customization features, as well as some of the game types. Alliance mode looks pretty sweet, something like an Assassin's Creed take on Gears of War's Wingman mode.
