As promised, Ubisoft has started its marketing efforts for Assassin's Creed: Brotherhood. An e-mail from the game's Abstergo Industries barely attempts to extend the fiction into reality, linking to a Flash-filled Ubisoft promotional website. Presumably, the teaser site provides insight into some of the weapons that may be used in the sequel's new multiplayer component, including an axe, fan, syringe, dagger and claw. (Solve the puzzle on the website to unveil yet another weapon: the switch blade.)
Some concept art (placed after the break) is buried in the site, possibly offering a clue as to how the story of Brotherhood will unfold. We're pretty certain these are rows of Animus machines waiting to be activated, but perhaps you can provide your own conspiracy theories.
