Man, the Cyberdisk was my favorite enemy and my least favorite at once. It was my favorite because it had a really cool design, and could fold in and out in all kinds of cool ways. It was my least favorite because they tend to wipe out my favorite soldiers in one or two shots. Cool concept art, thanks for sharing.
Oh man, it is so cool to find your work here. The Cyberdisc has so many moving parts... If I was handed that concept on paper, I wouldn't know where to start. You made it into something awesome, though.
