Minigun (Fallout 3)

The Minigun in Fallout 3 is the most commonly-encountered Big Gun, which means it is comparatively easy to find and repair, as well as one of the few Big Guns easy to find ammunition for; nearly every Super Mutant Brute encountered with one has at least 30 5mm Rounds for it. It is also carried extensively by Brotherhood of Steel units, Brotherhood Outcast Units, Enclave Soldiers, as well as some Raiders and Slavers. This is offset somewhat by the Minigun's high rate of fire quickly using up ammo. Though it does not use up ammo as quick as the Gatling Laser, the Minigun is designed as a sustained-firing weapon, and its rate of fire of over 40 rounds per second means that it can use up 240 rounds quickly. Because of this, those who intend to make use of it should buy additional ammunition, which is generally quite plentiful at shops.

When firing the Minigun without V.A.T.S., there is a wind-up time between holding the fire button and when it actually fires. It usually takes under a second to begin shooting. This can be negated by tapping the fire button repeatedly to keep it spinning while not actually firing.

Unique Minigun
There is a unique Minigun called Eugene which is available as a reward for Reilly's Rangers and has notably better firepower. Due to the ability to get Ranger Battle Armor through a trick and the difficulty of picking Brick's pocket, Eugene is arguably the better of the two rewards for that quest for those prepared to exploit the game.
