Bionics - Imperial Bionics: Bionic implants in the Imperium of Man come in all shapes and sizes, from memory upgrades for the Human brain to implanted weapons. Some of the more esoteric bionic implants are listed below. The tech-priests of the Adeptus Mechanicus are infamous for making use of extensive bionic implants, and some of the more exotic ones they create are used solely by them.This list is by no means exhaustive.Bionic Organs - For the wealthy or privileged of the Imperium, bionics can replace diseased or aged organs and therefore offer an increased life-span. Practically any organ can be replaced, even parts of the Human brain. The simplest bionics are mere replacements, while the more advanced increase the functionality and performance of the organ beyond its previous capacity.Bionic Senses - Such is the level of technology in certain parts of the Imperium that bionic senses can replace eyes, ears, noses, and even touch and taste. More advanced bionic senses can even produce effects of synaesthesia. Bionic eyes can increase a subject's visual spectrum, allowing the ability to see heat, ultraviolet light, other forms of energy, etc., as well as incorporating advanced weapons targeters and resistance to the effects of blinding flashes. The addition of digi-weapons into bionic eyes is also not unknown for high-ranking individuals. Bionic hearing can improve normal hearing to the point where the user can hear living creatures breathing, hearts beating, etc.Psi-Booster - A Psi-Booster increases activity in the part of the brain responsible for controlling psychic ability and accessing the psychic energies of the Warp. A person with one of these implants is usually a proficient psyker and has greater control over their powers compared to someone of the same psychic ability without a psi-booster.Mind Impulse Unit (MIU) - A Mind Impulse Unit (MIU) is a neural link between a sentient brain and a piece of electronic equipment, allowing an individual to control and monitor an electronic system by thought alone. MIUs are most commonly used by Space Marine Dreadnoughts and the crews of the gigantic Titans of the Adeptus Titanicus but are rarely seen elsewhere. The other uses entail shoulder-mounted weapons which allows the user to fire a weapon whilst keeping both hands free. In some rare cases the weapon is not shoulder-mounted but is carried as normal; the MIU allows the user a greater intimacy with his weapon's internal workings, such as ammunition count or barrel temperature. This is sometimes found amongst the Skitarii Tech-Guard of the Adeptus Mechanicus. Wireless MIUs also exist, although they are exceptionally rare and are used to control mechanical Familiars or certain types of servitor. This type of MIU is most common when the user cannot perform a common task himself (perhaps being too large to fit somewhere) or when he prefers to stay out of harm's way. A less advanced version of this same technology is the Throne Mechanicum used by the Nobles who pilot Imperial Knights.Implant Weaponry - An implanted weapon is one that has been grafted onto an existing limb, replacing a hand or occasionally the entire arm, and is controlled by a simpler MIU than that needed for a more sophisticated device. The obvious benefit of finer weapon control is substantially offset by the loss of hand or arm functionality outside of combat. This bionic is thus not especially practical, and is usually intended to intimidate, as the surgery used to graft them onto the user is often quite crude, leaving gruesome suture scars frightening above and beyond the "body horror" qualities of the implant itself. Another reason for implantation of bionic weapons is the user not being expected to need his arm for other tasks; this approach is most often seen in the cases of pit slave gladiators or certain types of Combat Servitor.Mechadendrites - Mechadendrites are mechanical tendrils used by the tech-adepts of the Adeptus Mechanicus to aid them in construction, maintenance, and research. These bionics contain small motors and actuators within their armoured shells and wave about the tech-priest implanted with them almost with a life of their own.Electoos - Electoos are metallic strips bonded sub-dermally that enable Tech-priests to channel limited amounts of electromagnetic energy; an extreme example are the renowned Electro-priests, who turn themselves into crackling founts of electricity in battle for the Adeptus Mechanicus. Electoos enable the user to directly absorb electromagnetic energy from equipment or other power sources and then expel it, with sometimes devastating results. They also can be used to store digital information and allow the user to interact directly with digital technologies such as cogitators.Rite of Pure Thought - The Rite of Pure Thought is considered an extreme measure even among some tech-priests. The creative, emotional, illogical right hemisphere of the Human brain is replaced with a cogitator (computer) linked directly to the logical left hemisphere. This frees the recipient of any irrationality and illogic, though it also essentially eliminates much of what makes him or her Human.
