This submachine gun filled National Guard arsenals after the Army replaced it with newer weapons. However, the "Grease Gun" was simple and cheap to manufacture so there are still quite a few still in use.

— Fallout 2 In-game description

The M3A1 "grease gun" SMG is a small gun in Fallout 2.

Background[edit | edit source]

Main article: Submachine gun

This submachine gun filled National Guard arsenals after the United States Army replaced it with newer weapons. However, the "Grease Gun" was simple and cheap to manufacture so there are still quite a few still in use. It's very powerful, but its .45 caliber rounds lack the bonuses of 10mm rounds.

Characteristics[edit | edit source]

These submachine guns are have a moderate fire rate, costing 1 AP less to fire than most other submachine guns. However, this benefit is limited by heavy ammunition, weighing 1 unit for every 10 shots. This makes the weapon rather cumbersome to carry, especially for a low Strength Chosen One or respective party members.

Locations[edit | edit source]

Female raiders between Broken Hills and Vault City carry these weapon, although they no longer spawn once the raider threat has been effectively eliminated. Big Jesus Mordino also gives the Warrior one once they kill Louis Salvatore.

They are occasionally sold at New Reno Arms.

Behind the scenes[edit | edit source]

The grease gun is based on its real life counterpart, the M3 submachine gun, which entered service in the United States Army on December 12, 1942. Designed as a cost-effective substitute for the .45 caliber Thompson submachine gun, it was nicknamed the "Grease Gun" due to its similarity in appearance to the mechanic's tool of the same name.
