With the game out soon (November!), it's nice to finally see a proper trailer devoted to its singleplayer campaign.
This collection of in-engine footage not only shows you the real game, it also shows you Ezio's extended suite of moves for the singleplayer component of the title, something that's been largely (though not entirely) overlooked in the game's marketing to date.
Pity about the music, though. I know, Ezio is being controlled by a Nolan North from the future, but when I see men stabbing men on the streets of Renaissance Italy, I don't' want to hear crooning!
