You idiots! Researching Carapace Armor should be the higher priority than Beam Weapons!
On a serious note, these cosplays are the cosplays of my dreams. Both he level of attention to the body armor as well as the spot on recreations of both rifles just give me warm fuzzy feelings inside. I do like how there's a little variation between the two of yours, with how Jeff's has the smoother rounder look and shoulder pads, meanwhile yours quite accomplishes the bulky look that the developers wanted in Enemy Unknown. All around, two spot on, awesome cosplays.
I'm working on my own XCOM cosplay. I'm using EVA foam for the vest and shoulder pieces. What did you guys use?
