A cyborg is a human being that has been modifed with artifical implants to make the person more effective in combat. The upgrades usually include strengthening of the bones, artifical muscle for extra strength, synthetic skin, and corrective eye surgery. It is common practice to brainwash a cyborg so they won't remember their past lives and to make them extremely loyal to the SWA. A cyborg is paired with a handler that will train them and direct them on missions. The lifespan of a cyborg is determined by how much "conditioning" they endure, the more conditioning the shorter the life they have. They also usually suffer from memory loss due to increased conditioning use.
