Best Fast Gunner Build in Once Human

Fast Gunner Build Basic Info

The Fast Gunner build lives up to its name—it's all about unleashing a rapid, relentless barrage of bullets. With each stack of Fast Gunner boosting your Fire Rate and Attack by 1% for 2 seconds (stacking up to 5 times), you're primed to shred through enemies.

Whether you're focusing on precision with weakspot hits or just laying down pure suppressive fire, this build is designed to make every shot count—and there will be a lot of them. It’s your go-to for raining bullets and quickly overwhelming foes!

Best Weapons for Fast Gunner Build in Once Human

Primary Weapon: MG4 - Predator

The MG4 - Predator is the beating heart of the Fast Gunner build because it perfectly complements the playstyle of shooting fast and hard. With a 40% chance to trigger the Fast Gunner skill on each hit, your Fire Rate and Attack stack up quickly. When those stacks hit a multiple of 5, you get a brief burst of infinite ammo, allowing you to unload without worry.

Plus, hitting the same target consecutively boosts your Weapon DMG by 2% per hit, up to 40%, and if you keep your magazine above 50%, you'll enjoy a hefty 40% Attack bonus. Fast Gunner thrives on speed and aggression, and this LMG is made for it!

Recommended Attachments

Here are the recommended attachments for the MG4 - Predator to elevate your Fast Gunner Build.

Secondary Weapon: AWS.338 - Bullseye

The AWS.338 - Bullseye or Bingo is perfect for the Fast Gunner build as a secondary weapon. When you switch to this weapon, it guarantees that the first hit triggers The Bull’s Eye, marking enemies and making them more vulnerable. This primes them for a relentless barrage from your MG4 - Predator. Plus, it boosts Weakspot DMG and Attack after those key weakspot hits, setting up for rapid, high-speed takedowns.

Melee: Stun Baton

The Stun Baton shines in the Fast Gunner Build in close quarters. Its light strikes inflict Power Surge, which cuts enemy accuracy by 40% and adds extra damage. Heavy strikes on these Power Surge targets then spread even more damage, ramping up your crowd control and damage output. It’s the perfect melee weapon to keep enemies in check while you unleash a flurry of bullets.

More stacks mean more speed, more firepower, and a whole lot more chaos—so slap this mask on and watch your enemies melt in a hailstorm of bullets.

Lonewolf Shoes for Shoes

Alternatives

For a precision-based build, consider switching to a combination of the Bastille Set and the Savior Set. Equipping 3 pieces of the Bastille Set enhances your firepower significantly. With increased Weapon DMG and Reload Speed, and a powerful Bastille state boost while crouching, this setup maximizes your damage output and efficiency.

Complementing this, the Savior Set provides crucial benefits with reduced Medicine Cooldown and additional Weapon and Status DMG when your HP is above 70%. This synergy boosts your damage capabilities and ensures you can handle tough situations with enhanced precision and survivability. Use Stabilized Style for Calibration if using this build.

Best Mods for Fast Gunner Build in Once Human

Best Weapon Mods

Precision Rush for Primary

Precision Rush amps up weakspot DMG by up to 45% while Fast Gunner is active, making your rapid-fire shots with the MG4 - Predator hit even harder. It's perfect for turning your quick bursts into high-damage strikes on enemy weak points.

Vulnerability Amplifier for Secondary

When paired with the AWS.338 - Bullseye or Bingo, the Vulnerability Amplifier mod boosts the Bull's Eye effect, increasing enemy vulnerability by an extra +8%. This makes it easier for your hailstorm of bullets to hit harder and faster when you switch back to your LMG.

Shock Diffusion for Melee

Shock Diffusion is fantastic for the Stun Baton because it spreads the baton's Power Surge status to nearby enemies within 5 meters. When you hit an enemy with Power Surge, it doesn’t stop there—another unlucky foe gets zapped too! This lets your Stun Baton chain the shock effect, making it even deadlier in crowd-control situations, and turning your melee strikes into a surge of chaos.
