One last update for the night before I go to bed. Finished the legs and the backpack. Going to move onto the last of the filler, armor bits, sword and shield over the weekend before I go back to the hands.

In the original game there were several upgrades you could give your robots. Newer/better boots, weapons, and backpacks. For the challenge this little guy is the melee only no ranged brawler. So the design of the backpack is meant to be more of a extra shield generator so he can take a few more hits while getting up close and personal with the bad guys.
