Started a new unit from the Legio Cybernetica today - the hard-to-kill Defender Robots. Will need to add some mechanodendrites and figure out a cool looking solution for adding a Hunter Killer missile.
The main body is from Bitspudlo.com, quite a dirty cast, but they do have some really nice looking stuff you don't see else where. The arms were way too tiny to be of any use here though, so they went straight into the bits box. Pretty happy with the head - really think it looks rather mean.
