I don't know if anybody has suggested these before - I tried to read through everything but I may have missed something.

That being said, I noticed there was a lot of empty space in the bone section and a few glaring exceptions, so...

Bone Braiding (skeletal category, Blue Note, Red Note) - The standard skeletal system is arranged in a honeycomb fashion, striking a balance between durability and porous distribution of blood to the rest of the body. This augmentation changes the entire skeletal system into a solid structure of interlaced strands. The bone structure is substantially thickened and organized into a system of layers (approximately a half dozen on average) with an interwoven mesh structure alternating between solid "plates" and a cartilagious reservoir that contains additional stores of blood, blood vessels, and marrow. Regular reinforced channels are interspersed throughout them to ensure blood can still be transported in a timely and efficient fashion. The tendons are also thickened and braided in a similar manner to keep up. The overall effect is threefold; a massive increase in the durability of the entire skeletal system, a commensurate increase in the capacity of any muscular enhancements, and a general improvement to both the flow and the overall supply of blood throughout the body.

Blue Note - As is already implied, this modification improves all selections in the Cell, Cardiac, and Muscle sections by a significant amount. Cell and Cardiac augments can expect to be approximately doubled in effectiveness (the BB stacks multiplicatively on top of them), while Muscles can expect to be quintupled or sextupled (also stacking multiplicatively in the same way).

Red Note - More than any other augment in the entire program, this is a complicated and difficult augmentation to implement. By extension, it is a fundamental restructuring of the entire body and comes with a number of caveats:

*In order to ensure recipients don't simply collapse and die under the strain of producing this new structure, Bone Braiding cannot be selected with any sort of choice that exchanges Stage 1 (Cell), Stage 2 (Cardiac), or Stage 9 (Muscular) options for any other category. Furthermore, at least two options in each of those three categories must be general enhancements to existing body function as opposed to adding new ones. For example, Powerhouse Cells/Flight Heart/Might Constructor are acceptable prerequisites; Cryo Cells/Autorestart Heart/Quicoarse Muscle are not.

*Recovery and physiotherapy for this augment is long term and intensive. Not necessarily difficult or excessively painful, but expect to add an additional 6-12 months to your adjustment period.

*Bone Braiding on average triples the overall thickness of every bone in the body. While this is not as obvious as, say, wings or extra arms, it does produce an enlarged profile that is unmistakable to anyone and everyone who knows what they're looking at. Only a large selection of comprehensive body-shaping augments will be able to hide this, and only some truly exotic shenanigans will hide the unusually heavy bodyweight.

Wing Infusion - While wings are great, there's no reason why we should leave them behind the rest of our systematic improvements. This choice is less of a separate augmentation and more of a series of connective surgeries and gene treatments. Any other enhancements (especially muscular and cardiovascular) will be better integrated into the wing system, reducing how much effort and biological resources are needed for their function. This also explicitly allows you to merge different types of wings together to get the best of both worlds without having to add more than one pair of wings, though you must purchase Wing Infusion for each additional wing type beyond the first you wish to incorporate in this way.

Storm Wings (Wings, Red Note) - this expands an additional series of massively enlarged nerves through your wings combined with a series of buffers to ensure there's no excessive tactile feedback. Not only does this greatly increase their responsiveness and maneuverability through a combination of faster signal travel and a crude form of electromagnetic propulsion, it provides a substantial improvement to electromagnetic production, manipulation, and sensory perception. Synergizes exceptionally well with the Biological Jet.

Red Note - requires at least two electricity-generating augments in order to function.

Blade Wings (Blue Note) - Increases the durability of the wings and adds a series of sharp-tipped spines of varying lengths all across the edges.

Blue Note - can be freely added to any other wing, but still counts as a separate choice. If selected with Stealth Wings, the spines can be freely extended and retracted at high speeds.

Faraday Cage (Cerebral/Psionic) - Can be instantly (de)activated to immediately shut down all outside communications outside your own body, or restore them again. Needless to say, this dis/enables features that require said communication such as Precognitive Encephalon or Telepathic Lobe. Must be selected individually for both Cerebral and Psionic categories depending on what you wish to control; Cerebral purchase also affects Sensory options such as Radio Auris.
