Since I d idn't like the idea of having the finest warriors o f the Imperium of Man being shepher ded around by a hand ful of people in jeans and t-shirts, I needed another option. I also had to have people fol low them around to make sure they wouldn't trip or fall over or bump t heir heads while walking through doorways. As a result, I had to settle for making them not we igh tons. While building the Space Marine costumes, I didn't have access to any of the technology of the 41st millennium. I n the game mythology th e ir a rmor is power assisted, which allows them to move the ir se veral ton s of mass with all the gra ce and fluidity of a dancer.
