Re: Captain America Easter Eggs Thread *Spoilers*
Dunno if it was an easter egg, or whether or not it was on purpose, but the guns had the same kinda "charging" sound as Iron Man's repulsor beams.
Wouldn't be a stretch to say Howard's research into the arc reactor is based upon the cosmic cube find and as such, Tony's own mini arc technology.
