The implants are transplanted by an Auto-Doc. A particular implant that differs in application from the other implants is the Implant GRX, an implant that can be injected directly like a stimpak without using an Auto-Doc. It causes a brief slowdown of the surroundings for two to three seconds and is destroyed afterward by the body. The user must have a resistant body to use it without side effects and the total limit per day is five at first but can be increased to ten.

Plans for the combat implant can be found in Vault 8 of Vault City in Fallout 2, and Doctor Usanagi of the Followers of the Apocalypse can perform the operation for both the physical implant and the special implant in the New Vegas Medical Clinic $$ Other special implants are available in Big MT in the Fallout: New Vegas add-on Old World Blues.
