Modern Warfare 3 got a new trailer today, showing off a host of the anticipated shooter's gameplay, including tons of weapons, classes and loadouts, as well as some deployable gadgets like an anti-missile system and an automated robot with machine-guns mounted to it. It's also good to see that the air-strike mechanic of previous games has remained intact! The whole "Hostile poor country invading New York" thing has been done before, though, and it would have been nice if Infinity Ward could have come up with a plot that was more…realistic.
