I dunno about the shininess due to the lighting and kinda small pic. Have to check when I go online again. Everything should be metal but I coulda goofed.
I can see the head size thing now that you mention it but am probly ok with it. Have to look online now that you've pointed it out. Until now, I thought Giz had a large melon (he's really small, too) but I hadn't noticed Jooc's overshadowed one - I focused more on his eyes I guess.
Gizmos is a name I actually managed to snag and keep in CoH. Lava was another good one but when I went away and came back it got changed. I had Ka-zar too but that got changed. And... hrrrrm.. I forget atm.. Gizmos was a gem tho for a game with unique names. He was Assault Rifle/Devices.
