List of Spartan Augmentations
Note: this list is taken, and quoted, directly from Halo: The Fall of Reach by Eric Nylund.
1. Carbide ceramic ossification: advanced material grafting onto skeletal structures to make bones virtually unbreakable. Recommended coverage not to exceed 3 percent total bone mass because of significant white blood cell necrosis. Specific risk for pre- and near-postpubescent adolescents:skeletal growth spurts may cause irreparable bone pulverization. (See attached case studies.)
2. Muscular enhancement injections: protein complex is injected intramuscularly to increase tissue density and decrease lactase recovery time. Risk: 5 percent of test subjects experience a fatal cardiac volume increase.
3. Catalytic thyroid implant: platinum pellet containing human growth hormone catalyst is implanted in the thyroid to boost growth of skeletal and muscle tissues. Risk: rare instances of elephantiasis. Suppressed sexual drive.
4. Occipital capillary reversal: submergence of and boosted blood vessel flow beneath the rods and cones of the subjects retina. Produces a marked visual perception increase. Risk: Risk: retinal rejection and detachment. Permanent blindness. (See attached autopsy reports.)
5. Superconducting fibrification of nueral dendrites: alteration of bioelectrical nerve transduction to shielded electronic transduction. Three hundred percent increase in subject reflexes. Anecdotal evidence of marked increase in intelligence, memory, and creativity. Risk: significant instances of Parkinson's disease and Fletcher's syndrome.
