I recall that an Optimus Prime magazine spread had a caption above his gun saying he could hit a flying target miles away. I'm guessing he'll use it to whack Starscream in fighter jet mode. And the sequence of Bumblebee riding shotgun and blasting from the girl's car was awesome. Not to mention Ironhide launching a missile doing the barrel roll. What other firearm sequences do you reckon there are? Or what do you wish to see?
