The Big Boomer is a unique weapon in Fallout: New Vegas.


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

A shotgun, also called a "scattergun," is a firearm designed to shoot a multitude of lead or steel balls of varying sizes, greatly increasing the weapon's hit potential. This makes it very effective at hunting game.[Non-game 1] However, the accuracy and power found at close range starts to diminish as the target gets farther away. Shotguns designed for the military's use are often called "combat shotguns."


Big Boomer expanded

The Big Boomer is a sawed-off shotgun with the same break action, 12 gauge that fires both shells at a time, delivering 14 pellets at a time instead of the typical 7 of other shotguns.

As compared to the standard sawed-off, the Big Boomer has a much darker color scheme with heavier rusting, and the words "Big Boomer" stenciled onto the grip in faded white paint. It excels over its default counterpart when it comes to sheer damage, delivering 20 more points of total possible damage. In addition, Big Boomer also has a slightly tighter spread, lower AP cost, and fires slightly faster. The only major drawback is that the common sawed-off shotgun is classified as a holdout weapon, whereas the Big Boomer is not.


Big Boomer can fire a total of about 395 times, or 790 standard rounds, the equivalent of 395 reloads, from full condition before breaking. This is exactly the same amount as its common variant.

Behind the scenes

Within the game's files exists an unused texture for the Big Boomer.[1] It uses the Fallout 3 model and only differs from that in the color of the wood and the words Big Boomer written down the side of the handgrip.

  1. Fallout 2d20 Rulebook p. 98: "Before the Great War, double-barrel shotguns were mainly used for hunting and home defense, and this has changed little. They are break-action and come in an either a side-by-side or over-and-under barrel configuration. Simple to make and maintain, these shotguns are seen frequently in the Commonwealth and the rest of the wasteland."
