Skeletonics is a group of Japanese exoskeleton artisans who built an exosuit for the express purposes of A.) looking awesome; and B.) messing with their pals.
Nobody will be wrangling with a queen alien in the Skeletonics rig, but it's got the maneuverability to steal soft drinks and fire rockets. You can check out their schematics in the first half of the video, but the action really starts at 3:11, when one of the Skeletonics dons the exosuit. For more no-budget power armor, see this giant cardboard mecha.
