Greased Lightning is a unique melee weapon added with the Fallout: New Vegas add-on Gun Runners' Arsenal.


Greased Lightning is a power fist variant with an extra hydraulic shock. It is powered by a nuclear battery using the emissions from a radioactive isotope to generate electricity that greatly enhances the speed of its execution mechanism. It has nickel black, metal plating with a radiation symbol painted on the top, a warning "Radiation risk" on the right side, and each of its three tubes are a cream color. It also sports 33 tally marks on the side.


Greased Lightning has a lower damage than most high level Unarmed weapons in the game, but its extremely high attack speed gives it a higher DPS than most. Greased Lightning is also an improved holdout weapon, meaning it can be concealed if the players Sneak skill is 50 or greater.

  • This weapon makes Unarmed combat easier, since you are able to perform special unarmed attacks at an extremely fast speed.
  • It makes opponents fly into the air or skid across the ground when killed.
  • If the player is hostile to the Brotherhood of Steel and Torres is set to respawn (see Torres bugs), Greased Lightning may be impossible to obtain.

Behind the scenes

  • "Faster than greased lightning" is an American idiom for describing something of great speed. The phrase was popular in the 1950's and 60's and is an allusion to the weapon's high attack speed.
