The cybernetic labs on the Mars Planetary Corporations bases create semi human augmented cyborg soldiers and scouts in order to trade them to other advanced ET species as part of the slave organization which acquires medical serums to stop diseases or end the aging process, receiving technology that is hundreds of years more advanced that they can implement for building better ships, colony facilities, various space stations weaponry, healing medical pods, etc. as well as gaining rights for more trading routes in space and access to planets where they can build their colonies. The PLC labs use both living and dead body parts for harvesting purposes in order to merge cybernetic technology with the human body component.
Human bones can be used for cyborg creation, only the best tissue matter, body parts, and DNA is selected for splicing with cybernetic technology. There are lab technicians who monitor the selection processes for building the human cyborgs.
