Cybernetics

Cybernetic Technology is commonly used by humanity to replace damaged parts of one's body, or to enhance a person to heights formerly unthinkable. This technology is common on the battlefield, because it can be used to compensate for human weakness or to enhance an already existing edge even further. It does not come without its problems though, since cybertech is expensive, needs maintenance, and doesn't grow back when damaged. Cybernetic users often to seek ways to mitigate this price. It's not uncommon to see cybernetics with holo ads scrolling across there frame in the non military issues of course.
The benefactor of cybernetics can be from any subrace of humanity, expect Mancers as they need their natural body to channel and control their power, and Superhumans to an extend since their strength and speed often does not apply to their cybernetic limbs.
