Tesla-Beaton Prototype

FO76 publicteam xpd.pngFor an overview of Tesla cannon models, see Tesla cannon.

The Tesla-Beaton Prototype is a unique weapon in Fallout: New Vegas.


This section is transcluded from Tesla Cannon. To change it, please edit the transcluded page.

The Tesla Cannon was designed by the U.S. Government, as a sister project to Poseidon Energy's Solar Cannon and served as a lightweight, anti-tank energy weapon.[1][2] The cover of Future Weapons Today mentions them being "light and compact".[3] During the conflict between the Brotherhood and the Enclave in the Capital Wasteland, Brotherhood scribes worked to build their own Tesla Cannons utilizing a Tesla Coil to more effectively counter the Enclave's vertibirds.[4]


The Tesla-Beaton Prototype is a unique variant of the Tesla Cannon. Prior to Patch, each shot expended 45 Electron Charge Packs, but it now expends six Electron Charge Packs per shot, with a magazine capacity of 24. Also, the patch removed the Prototype's AOE blast damage. Unlike the original Tesla Cannon, it only has half the HP. This is likely due to it being in the prototype stage. Because of this issue, the need for constant repair makes it a less practical weapon for repeated use.


The Tesla-Beaton Prototype can fire a total of about 195 times using standard packs, the equivalent of 49 reloads, from full condition before breaking.

The Tesla-Beaton Prototype can be found at the Crashed Vertibird next to a skeleton, near the Old Nuclear Test Site far southeast. Use caution, however, as there may be up to six Hardened Mister Gutsies and four Hardened Sentry Bots standing guard.


  • The Tesla-Beaton Prototype is one of the most expensive weapons to repair to 100% from poor condition at over 20,000 Caps, rivaling Gatling Lasers and Plasma Casters.
  • The glow on the outside shows the arcing electricity to be orange in color, but if looking down the barrel in the third person, it looks green.
  • Even though the Tesla-Beaton uses six Electron Charge Packs per shot, it's only possible to get a single Drained Electron Charge Pack from firing it.
  • Due to it previously firing only one shot per reload, it ejects Electron Charge Packs every shot, which is strange, considering only one is loaded. Also, the Electron Charge Pack will not appear after one shot is fired, and the end of the cannon is retracted, but it still ejects another per shot.

  • Playstation 3Playstation 3 In some cases, the clear encasing on the cannon will not show the Tesla coil animation and instead always stay glowing orange, reloading a saved game or fast traveling will fix this.
  • Playstation 3Playstation 3 Xbox 360Xbox 360 After patch 1.5/, when looking from the third person, the Tesla-Beaton Prototype will eject the Electron Charge Pack in the back of the cannon after the first shot, and then seemingly eject Electron Charge Packs out of nowhere during any shots after the first one. This can be remedied by reloading after each shot, though it is not recommended.

Primarily intended to be a crowd control device, the weapon's instability and high radiation emittance resulted in the project being abandoned."
  2. Creation Club description: "Designed by the U.S. government as a lightweight, anti-tank energy weapon, the Tesla cannon delivers a massive jolt to any unfortunate soul who stands in its path. Includes custom modifications and a new quest that has you track the whereabouts of a missing Gunner crew!"

    Paladin Tristan: "Hopefully you'll be able to find a Tesla coil, an experimental device from before the war. Our scribes need it to complete a little surprise they've been preparing for the Enclave. Get there, get the coil, and get back as safely and quickly as possible. Any questions?"
