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. It has 30% faster attack speed, 0.5 lower weight, is 25% more durable compared to a standard grenade rifle and has a unique attribute of making grenades fired from it move twice as fast as normal.

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 cartoon drawing of an angry beaver with red eyes holding a battle rifle on the stock.

Variants

 * Grenade rifle, the common variant.
 * Mercenary's grenade rifle Fnv-mercenarypack (1).jpg, a unique variant of the grenade rifle that is slightly lighter.
 * Great Bear grenade rifle, a unique variant of the grenade rifle that has more damaging projectiles (not explosions).
 * Red Victory grenade rifle, a unique variant of the grenade rifle with a faster rate of fire.

Location
Nellis array, inside the building, south/southeast of the generator switches during or after the quest Ant Misbehavin'. It is between two broken generators, by a skeleton.

Behind the scenes

 * The name is a reference to the nickname "Thumper", given to the real life M79 grenade launcher (which the grenade rifle is based upon) by American soldiers.

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.
 * In third person view when you run the weapon will fall, holstered or holding, and may "follow" you. It is still visible in first person view. Unequipping it then re-equipping will remedy the problem.
 * If a limb is crippled right after firing, you will not have to reload.
