My brother and I are making a Halo CE version of the Master Chief, and we have plans for many cool add ons. We have much of it made on paper from Armorsmith, and upon finding fiberglass very expensive, we used papier mache'. I will attached photos below as we get each part finished. Some of the pieces we riveted sheet metal into it. There was lots of testing to get the right batch of papier mache', but we figured it out.
