The Gauss Minigun in Fallout 76 is a powerhouse heavy weapon that combines high-speed automatic fire with devastating energy damage. As one of the most advanced ballistic weapons in the Wasteland, it’s a favorite among high-level players who want to tear through enemies with sheer force. This guide breaks down everything you need to know about acquiring, modifying, and using the Gauss Minigun effectively.

What Is the Gauss Minigun?

The Gauss Minigun is a heavy weapon introduced in the Wastelanders update. It uses 2mm EC ammo, which delivers energy-based ballistic damage. Unlike standard miniguns, the Gauss variant has a charge-up mechanic that increases its damage output the longer you hold the trigger, rewarding players who maintain sustained fire.

It’s an endgame weapon intended for high-level characters who specialize in the Heavy Guns perk line and are looking for a blend of fire rate and energy devastation.

How to Get the Gauss Minigun

To get your hands on the Gauss Minigun in Fallout 76, you’ll need to visit Mortimer, a vendor located in The Crater. He only sells the plans to players who are at least Ally rank with the Raiders. Here’s what you’ll need:

• Raider reputation at Ally level

• 750 Gold Bullion for the plan

• Access to crafting benches and high-tier components

Alternatively, the Gauss Minigun may occasionally appear in Daily Ops rewards or other seasonal events, but these are less reliable sources.

Crafting and Modifications

Once you’ve acquired the plan, you can craft the weapon at any Weapons Workbench, provided you have enough 2mm EC rounds and crafting components.

Key Mods:

• Charging Barrel – Boosts the damage potential by increasing charge speed.

• Reflex Sight – Improves accuracy and reduces AP cost in VATS.

• Tesla Coil Capacitor – Adds a small AOE electrical damage to each shot.

Most upgrades will require Legendary Modules, which are obtained through Purveyor Murmrgh at The Rusty Pick.

Best Perk Build for the Gauss Minigun

To fully utilize the Gauss Minigun in Fallout 76, you’ll want to build your character around the Heavy Gunner perks and focus on maximizing damage, ammo efficiency, and survivability. Recommended perks include:

• Heavy Gunner / Expert / Master Heavy Gunner – Increases base damage.

• Stabilized – Boosts accuracy and ignores enemy armor in Power Armor.

• Bear Arms – Reduces weapon weight.

• Lock and Load – Speeds up reload time.

If you're using Power Armor, the synergy with Stabilized is essential for maximizing damage output.

Combat Tips and Strategy

• Pre-Charge Before Engagement: Since the Gauss Minigun charges up, it’s smart to begin firing just before rounding corners or entering combat.

• Use in Power Armor: Power Armor is almost mandatory to offset the weight and to take advantage of Stabilized.

• Keep Ammo Stocked: 2mm EC ammo can run out quickly. Use crafting and ammo converter stations to keep your reserves up.

• Against Bosses: The sustained DPS makes it excellent for boss fights or public event enemies with large health pools.

Is the Gauss Minigun Worth It?

For players running a heavy weapon build and who have access to Gold Bullion vendors, the Gauss Minigun in Fallout 76 is absolutely worth it. While it doesn’t offer the pinpoint accuracy of other weapons, its sheer suppressive power and explosive potential make it one of the most satisfying weapons to use in PvE content.

If you enjoy melting through waves of enemies, mowing down bosses, or simply making a ton of noise with a high-tech cannon, this weapon delivers.

The Gauss Minigun in Fallout 76 is a unique endgame weapon that rewards planning, resource investment, and the right perk setup. While not for everyone—especially those not specced into heavy weapons—it offers a thrilling, high-damage experience for players who embrace its charge mechanic and brutal firepower.

Whether you’re clearing Daily Ops, diving into public events, or just want to feel like a walking tank, the Gauss Minigun deserves a place in your arsenal.
