Human VATS Heavy Gunner
Heavy Gunner / Power Armor TankA raid-viable Power Armor tank built around chaining VATS critical hits with heavy weapons after the April 21st update. The build pivots from nerfed defensive layers to the Limit Breaking armor mod, which stacks up to 50% AP cost reduction across Union Power Armor, enabling constant heavy-weapon crits. Ten active mutations feed the Mutants legendary effect for stacked damage reduction, while the Tesla Cannon and Gauss Minigun cover sustained DPS and raid boss shield-breaking respectively.
Damage
VATS headshots with +90% crit damage (Better Criticals) + +100 crit damage (Blight Soup). Stacked Furious at 9 kills adds further scaling. Eagle Eyes adds +50% crit damage on top.
Survivability
485/295/265 full-set DR/ER/RR. Up to 5% flat damage reduction per piece via Mutants (10 mutations). Power Armor base resistances. Rejuvenated sustain when buffed.
Boss
Gauss Minigun explosive rounds break EN06 shield. Tesla Cannon handles final boss sustained DPS. Taking One for the Team multiplies the full team's damage by 40% during boss pulls.

Heavy Gunner
The perk card line governing all oversized weapons in Appalachia, including Tesla Cannons, Gauss Miniguns, and Pepper Shakers. These perks directly scale all heavy weapon damage and define the build's raw DPS ceiling.

Primary DPS weapon for most content. Arc electricity jumps from the initial target to nearby enemies for full damage. The Direct Current Muzzle config deals higher single-target damage, while Alternate Current is better for crowds. Furious stacks up to 9 kills for maximum damage scaling.

How to Obtain


Best-in-slot armor for this build. The full six-piece set provides the highest combined resistances available alongside a poison immunity bonus. The Mutants legendary effect stacks a flat 5% damage reduction per active mutation per piece, while Limit Breaking on all six pieces cuts critical hit AP costs by 50% total — the key mechanic enabling constant VATS crit fire.

How to Obtain
Pre-combat food buffs are mandatory for the build's crit damage ceiling. Blight Soup adds +100 critical hit damage for 30 minutes. Brain Fungus Soup boosts Intelligence for increased overall damage scaling. Canned Coffee or Company Tea keeps Action Points regenerating while in VATS, enabling the sustained crit chain that defines the build.
Combat Strategy
- ▸Consume Blight Soup for +100 critical hit damage lasting 30 minutes. With Herbivore mutation active this bonus is doubled. Time this buff before entering the raid instance.
- ▸Eat Brain Fungus Soup for an Intelligence boost that scales overall damage. Both soups count as plant-based food, activating Rejuvenated and Herbivore bonuses simultaneously.
- ▸Drink Canned Coffee or Company Tea immediately before pulling enemies. These drinks trigger constant AP regeneration while in VATS, enabling the sustained crit chain loop.
- ▸Enter VATS and fire continuously. Each hit builds Concentrated Fire stacks (+12% accuracy, +3% damage at Rank 3 per hit, up to 20 stacks) while simultaneously charging the critical meter via Four Leaf Clover.
- ▸Fire critical hits whenever the crit meter fills — Critical Savvy (-35% AP cost) and Limit Breaking (-50% AP cost per piece) make crits almost free. Chain crits as fast as the meter allows.
- ▸Avoid reloading mid-VATS if Bullet Storm stacks are active. All stacks reset on reload. Drain the magazine before cycling to preserve the Bear Arms damage bonus.
- ▸EN06 (First Raid Boss): Open with the Gauss Minigun to break the shield with its inherent explosive damage bonus. Stack Furious by targeting consistently. Once the shield breaks, swap to Tesla Cannon.
- ▸Final Snake Boss: Tesla Cannon is the primary weapon. Stay at medium range to keep both arc-chain damage and Direct Current muzzle single-target damage active. Use Tenderizer to debuff resistance for the whole team.
- ▸Taking One for the Team triggers whenever a boss attacks you — position to draw aggro so the team benefits from the 40% incoming damage amplifier on the boss.
