Thump-Thump is a unique weapon in Fallout: New Vegas.


Thump-Thump is a unique grenade rifle which has the extended range of a barrel extension mod found in its common counterparts and enhanced AoE radius. It also has 30% faster attack speed, 0.5 lower weight, and is 25% more durable compared to a standard grenade rifle. It also has a unique texture and the words "Thump-Thump" scrawled on the side with an arrow pointing towards the muzzle. There is also a drawing of an angry beaver with red eyes holding a rifle on the stock. Standard 40mm grenades fired from this weapon will have twice the velocity as ones fired from other grenade rifles.


Thump-Thump can fire a total of about 620 standard rounds from full condition before breaking.

Nellis array - Inside the building, south/southeast of the generator switches during or after the quest Ant Misbehavin'. It is next to two broken generators, by a skeleton.


  • If the Boomers are killed for Mr. House or Caesar's Legion before obtaining the Nellis generator key from Raquel, Thump-Thump cannot be obtained. The building's door is unpickable and can only be opened with the key, which does not appear on her body if she dies.
  • Thump-Thump uses a unique projectile to give it the projectile speed bonus, meaning said bonus only affects standard 40mm grenades.

Behind the scenesEdit

  • Thump-Thump is based on the real-world M79,[1] a US grenade launcher developed in the early sixties.
  • The name Thump-Thump is a reference to "Thumper," one of the nicknames US Servicemen gave the M79 due to its distinctive report.
