I don't know if you guys have seen this, but it's thirteen minutes of gameplay from MW3.

In keeping with the finest traditions of the Modern Warfare series, 1) it looks really fun, 2) there are gaping plot holes.
Long story short, you have to fight your way to the NYSE on foot, fighting Russians troops and Hinds along the way, to get to the roof of the NYSE to blow up some antenna/transmitter thingy. Not "collect intel from," or "find," but blow up. Once that's done, they send a Blackhawk to pick you up DIRECTLY from the rooftop. So, instead of just sending in gunships, or even that same Blackhawk to blow up something ON THE ROOF, they make you fight street by street, house by house. (Did I mention it looks really fun? Because it looks really fun.)
