This implant, called the logic co-processor, can be bought from Doctor Usanagi at the New Vegas medical clinic and increases the player character's Intelligence by one. The bonus from this implant will increase the number of skill points that are gained per level. The additional Intelligence point grants an additional skill point only at every other level.
If one's Intelligence is less than 4, Doctor Usanagi will take pity on the Courier and offer a discount of 1000 caps for this implant. This is similar to an interaction with Dr. Lorri in Fallout who offered implants and would offer the intelligence implant at a significant discount.
- If you are offered the low-Intelligence discount but do not purchase the implant and then leave the hospital, when you return and speak to Usanagi next time she will no longer offer this implant - discounted or otherwise.[verified]
- player.modav console command to temporarily drop your INT below 4. Once the effects wears off, the intelligence implant will be for sale again. player.setav intelligence 3 corrects this. [verified] The option "to be smarter" will also be missing from the dialog if you use alcohol, chems or the
