Re: Iron Man's weapons.
Iron Man didn't really use his whole arsenal of weapons in Iron Man 2. He mostly stuck to repulsors. I didn't see his unibeam, and he didn't fire any missles from his gauntlets. I didn't see a trace of pulse bolts either, and he should've had an EMP dampening field (like the one he borrowed from Force in the comics). He used more weaponry in the first movie, especially during the aerial chase scene with the fighter planes.
