They are still pretty much human, but my have different enhanced senses, modified/enhanced extremities; I once played the PnP with a person who's character had "hand like" (They were like talons that gave them a crazy advantage in micro and zero gravity.) feet and natural night vision. stuff like that, nothing Frankenstein would do, but more of practical modification. If this group goes on long enough we can get into the actual game and see some crazy stuff in the shady parts of New Humanity.
