Thump-Thump

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

Characteristics
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 a 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.

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

Behind the scenes

 * Thump-Thump is based on the real-world M79, a U.S. grenade launcher developed in the early sixties.
 * The name Thump-Thump is a reference to "Thumper," one of the nicknames U.S. service members gave the M79 due to its distinctive report.

Bugs

 * On some occasions Thump-Thump will not inflict any damage to the target. If this happens you may also not cause any damage while using V.A.T.S.
 * Sometimes it removes the 1st person texture and turns invisible in 3rd person.
