Implant

An implant is a medical device manufactured to enhance an existing biological structure.

The implants are transplanted by an Auto-Doc. The modifications may be from a small implant or from metal plates, like combat armor plates, which are surgically implanted into the patient's skeleton. The combat implant can be improved once but, given the scars left, the player ends up losing 1 point in Charisma.

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 clinic in Fallout: New Vegas.
