Implant Y-3

Implant Y-3 is a special perk in the Fallout: New Vegas add-on Old World Blues.

Obtaining
This perk is available to the player after finding the Auto-Doc Upgrade: Implant Y-3 in the Z-9 Crotalus DNA preservation lab. It can then be purchased from the Auto-Doc in The Sink for 12,000 caps.

Effects

 * Removes radiation taken when drinking dirty or irradiated water, soft drinks, and alcohol from the Pip-Boy inventory.
 * The message "Implant Y-3 removed ingested radiation" will appear on-screen.
 * The amount of radiation removed is dependent on the player's current radiation resistance level.
 * It has a lesser effect when drinking from irradiated faucets, toilets, urinals and water ponds. Radiation effects are lowered to +1 rad.
 * There is no on-screen message when drinking from these sources.

Behind the scenes

 * All Old World Blues implant perks use this image, and they are the only characteristics in the SPECIAL that have no Vault Boy or Vault Girl included in the image.
