Many explorers and mercenaries modify their own bodies with technological or biological gear called augmentations. These are modifications to your body that give you special abilities and bonuses. Once installed, they become a part of your body and generally can’t be affected by abilities that destroy or disable objects or target technological items or creatures. As far as attacks and abilities are concerned, a cybernetic or vat-grown arm is no more (or less) vulnerable than your original biological limb.
All augmentations have a system entry indicating the part of the body into which it must be installed. You can’t have more than one augmentation on the same part of your body.
In some cases, such as with augmentations installed in limbs, you can install an augmentation into a single general type of body part, such as any single one of your feet or hands. In these cases, the augmentation lists the acceptable body parts into which the augmentation can be installed. You can install a single augmentation on each limb of which you have multiples. For example, if you’re a kasatha, you could install a separate augmentation on each of your four hands, as long as each of those augmentations requires only a single hand.
If an augmentation requires multiple limbs for installation—such as climbing suckers, which require all feet, or a speed suspension, which requires all legs—the augmentation’s systems entry indicates that requirement. The augmentation’s description will also indicate whether a limb-based upgrade requires the replacement of a limb or the augmentation of an existing limb. In the case of augmentations that specifically replace a lost limb, such as a polyhand or a prosthetic limb, you cannot attach such an augmentation to an existing limb, due to the way these upgrades are manufactured.
Common Systems: Although exceptions do exist, most augmentations require installation into one of the following body systems: arm (or all arms), brain, ears, eyes, foot (or all feet), hand (or all hands), heart, leg (or all legs), lungs, spinal column, skin, and throat.
Getting an augmentation installed requires the services of a professional cybernetic surgeon or someone with ranks in Medicine equal to the level of the augmentation. A session with a cybernetic surgeon usually takes 1 hour per level of the augmentation. The price of such implantation procedures is included in the prices listed for each augmentation.
You might want to have an augmentation removed, usually because you want to install a different one in the same system of your body. This removal usually occurs during surgery to install new cybernetics. Biotech usually kills off the old augmentation while it’s integrating with your body, allowing you to purge the dead biotech naturally. Because augmentations are coded to your body, it’s not possible to resell an old augmentation, nor can you reimplant one into a different person. The price of a new augmentation includes the price and time to remove the old augmentation.
Most augmentations work continuously. Those requiring some degree of control are plugged into your nervous system, and you can turn them on or off as a standard action unless otherwise noted. For example, you could activate or deactivate cybernetics in your eyes to observe different visual phenomena.
