During Release For Iron Man 2, Paramount Trots Out Real Iron Man Suit
Here is the XOS 2, a creation of Raytheon that is billed as the closest thing to an Iron Man suit but is really just a super sick exoskeleton that allows for increased strength without having to be tethered to a power source.
Also, Paramount demo’d one of these as a promotion for the home video release of Iron Man 2. Pretty boss move by them.
