This can of worms has been opened by the RT book, but not really addressed as everyone fawns over ships. (Myself included)

Have any of you made anything new?

Personally, I disposed of the penalty on Best Quality Muscle Graft's Agility penalty, and instead assigned it to the poor quality version. Logically, a Best Quality one would be denser rather then bulkier, or contain exotic polymers that expand and contract with greater force then muscle fibers.

Archeobiotechnology:

Pit Organ: This sensory enhancment allows the subject to sense heat emitting objects, even in total darkness. Treat as Preysense goggles.

Haemological Filter: This enhancment to the kidneys allows for improved filtration of impurities from the bloodstream. +30 to Toughness tests vs Disease or Poisons.

This is not very relevant, but the five senses trope is a bit of a myth as we actually have several more, including a heat sense. It's often lumped in with touch but isn't really the same, as you can tell the difference between lifting a mug and burning a finger. Just put your hand near a radiator to test this. Heat sense goggles take the premise of translating something like heat sense into a more developed (and therefore more detailed) media such as vision. There are others too such as pressure and balance.

Sorry, a bit of a tangent.
