From publisher blurb: Metal bones are the mark of many strange experimental subjects ranging from living weapons to killer robots, flesh-coated cyborgs and countless others. A Combat Endoskeleton is a mechanical skeleton that either coats or replaces the Hero’s biological frame. Along with this difference under the skin, the Hero is implanted with an array of cybernetic upgrades and deadly weaponries that make their already formidable powers ever-more dangerous!
