Assassin's Creed: Brotherhood Multiplayer Trailer

I originally thought Assassin's Creed Brotherhood would be a host of unmanageable, unnecessary, and unwanted multiplayer modes, strapped to the back of a single player experience that would feel essential before purchase and mundane afterwards.

Unfortunately, that attitude is betraying me as I watch this trailer.  Who knows!  Maybe Assassin's Creed Multiplayer can be done in a way that is both exciting and fun.  What do you think?
