The Unofficial Warhammer 40k Costume and Prop Archive
Location: Portsmouth, New Hampshire
Materials: "Shell made entirely out of duct tape and cardboard, I also added LED lights to all the ports and eyes, and working computer fans cycled air in the mask and backpack. I also added a 2 liter water bottler to the backpack that had a straw that lead to just below the mask. Finally, I added a voice modulator to the mask to sound like a space marine."
