Fallout: New Vegas implants

When talking to Doctor Usanagi in the New Vegas Medical Clinic she reveals that she sells implants to augment your physical abilities, and two special implants to augment your combat performance. The physical implants behave in the same manner as the Intense Training perk, permanently raising that ability one point.

General
When installing implants, Usanagi will check your Endurance to determine how many you can handle. The total number of implants you can receive is equal to your base Endurance plus any additional increases to Endurance via Intense Training. The Endurance implant she sells is not counted by this check. For example, if your starting endurance is 6, you can get 6 of the 9 possible implants. If you boost endurance to 7 with the implant, you still will only be able to get a total of 6 implants. Endurance-increasing items (chems like Buffout or apparel like Wasteland outfit) will not be taken in account for implants, either, as they are temporary. It is only possible to purchase one of each implant type.

Since the effects of implants are counted as a permanent increase to your SPECIAL, they will affect the perks available to you when you level up, so long as the increased stat meets the requirement.

Physical Implant
Physical implants cost 4,000 caps each, and only one of each type can be purchased. You cannot raise a natural stat above 10; i.e. if you started with a base Intelligence of 10, you cannot raise it to 11. Should a stat be raised to 10 with the Intense Training perk, the game will permit you to buy that implant without benefit.

There are 7 physical implants, 1 for each of the S.P.E.C.I.A.L. s:


 * Strength: Hypertrophy Accelerator
 * Perception: Optics Enhancer
 * Endurance: Nociception Regulator
 * Charisma: Empathy Synthesizer
 * Intelligence: Logic Co-Processor
 * Agility: Reflex Booster
 * Luck: Probability Calculator

Special Implant
Special implants add special effects.


 * NEMEAN Sub-Dermal Armor: Adds 4 to your Damage Threshold. The price is 8,000 caps.
 * PHOENIX Monocyte Breeder: Adds a hitpoint regeneration effect mimicking the Solar Powered perk (1 HP / 5 sec), only it is always active. The price is 12,000 caps.

Bugs

 * Sometimes purchasing the strength implant does not increase strength.
 * Sometimes there is no dialogue option for the intelligence implant.
 * If you experience this bug it may be fixed by temporarily lowering intelligence with alcohol.
 * If you buy an implant and stay in dialog with Dr. Usanagi then you can buy another implant for the same SPECIAL
