You gain a non-addictive subdermal Turbo (chem) injector. This perk may be taken twice, with the second rank increasing the effect from 2 to 3 seconds and the uses per day from 5 to 10.”— In-game description
Implant GRX is a non-addictive drug with the same effects as turbo; slowing down your surroundings to give you more time to act. It is accessed from your inventory in the Aid section of your Pip Boy, with the supply replenished every 24 in-game hours. This perk can be taken twice, for enhanced effects:
- Rank 1: it can be used 5 times a day, and lasts 2 (pre-Turbo) seconds per dose.
- Rank 2: it can be used 10 times a day, and lasts 3 (pre-Turbo) seconds per dose.
The effects of multiple doses are cumulative.
- The stated duration is for time before it's been slowed by the turbo effect. As a result, the "real" duration is much longer.
- With the Chemist and Day Tripper perks, rank 2 of Implant GRX will last 8 seconds in real time with each use. With Logan's Loophole, Chemist, and Day Tripper, the duration of each use (rank 1) is 16 seconds in real time.
- Keep in mind however, that rank 2 of this perk cannot be taken with Logan's Loophole.
- Due to the high Endurance requirement, this perk is realistically at its most efficient on characters that operate in melee range. Acquiring Chemist, also a strong perk on such characters, makes Implant GRX highly synergistic on melee characters.
- The Fast Times perk does not affect Implant GRX duration.
- Like all chems, the duration of Implant GRX will stack with multiple doses. This can result in a lengthy duration of slow motion by consuming many doses at once (up to 80 seconds in real time using all 10 doses with GRX rank 2, Day Tripper and Chemist).
- Uses of Implant GRX cannot be hotkeyed.
- The effects of the implant are not cumulative with the chem turbo. Doses of turbo taken at the same time will be wasted.
Behind the scenesEdit
- The image for this perk is the same as the icon for the RobCo processor widget, a quest item in Fallout 3.
- All implant perks from Old World Blues use this image, and they are the only perks that have no Vault Boy or Vault Girl included in the image.
- The name is an obvious reference to the opposing car, the GRX, from the two-part episode of Speed Racer "The Fastest Car on Earth."
