Best Weapons for Fast Gunner Build in Once Human

Best Weapons for Fast Gunner Build
Primary Secondary Melee

Primary Weapon: MG4 - Predator

Once Human - MG4 Predator Fast Gunner Build
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!

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

Secondary Weapon: AWS.338 - Bullseye

Once Human - AWS.338 - Bullseye Fast Gunner Build
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

Once Human - Stun Baton Fast Gunner Build
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.

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.
