Ben Gilbert of Joystiq shares his Modern Warfare 3 Spec Ops experience:
As I carefully sniped oncoming baddies, Alex — dressed in a “Juggernaut” bomb suit, a first for the series — slowly lumbered around, dodging bullets/missiles/helicopters/tanks (seriously) while I assisted from above. Moreover, his ability to locate the remaining IEDs was based on me tossing up a UAV and spotting them from above, all the while dodging bullets/rockets myself. Of course, that meant I got to regularly drop missiles from said UAV onto the aforementioned waves of antagonists. Points!
That sounds like insane amounts of fun. I am definitely starting to get excited about Modern Warfare 3.
