The Fast Gunner weapon effect in Once Human is all about shooting harder and faster. It increases a weapon's fire rate and damage output every time it's triggered, often resulting in ridiculously high DPS when combined with the right mods, buffs, and armor effects.

Despite not being as flashy or complicated as something like a Power Surge build in Once Human, Fast Gunner setups can compete with the top dogs of the DPS charts while giving players the satisfaction of unloading countless bullets into a poor monster's face. Here's a starter Fast Gunner guide for players who want to explore this fun and satisfying build path.

Note

Prioritize getting Magazine Capacity, Crit stats, Weapon DMG, and Reload Speed

This build aims to stuff as much raw Weapon DMG buffs into the MG4 Predator via mods, armor pieces, and weapon effects like Fortress Warfare. Players will often get double the Weapon DMG on the MG4 Predator just by shooting enemies, essentially turning each hit into a critical strike that can also critically strike. This is a good base for a Fast Gunner build as it offers reliable DPS against all enemies while being very flexible when it comes to armor, mods, and secondary weapon choices.

Primary Weapon

Description of the MG4 Predator in Once Human
Once Human MG4 Predator description

The MG4 Predator comes with the following attributes:

  • 40% chance to trigger Fast Gunner when hitting an enemy.
  • The top half of the magazine deals 40% more Weapon DMG.
  • When Fast Gunner stacks reach a multiple of 5, gain infinite ammo for 0.5s.
  • Hitting the same target consecutively increases your Weapon DMG against that target by up to 40%.

Weapon Calibration Blueprints in Once Human can drastically affect how a gun performs. For this build, we'll be using the Rapid Shot Style (preferably with dual Crit stats) to increase our fire rate by up to 15%. This will reduce the already-poor Accuracy of the MG4, however. To compensate, use the following weapon accessories:

  • Hammer Compensator: +9 Accuracy, +19 Stability
  • Compact Reflex Sight: 2.0x Zoom, +12 Stability, +10% Aiming Speed
  • Cobra Grip: +20 Accuracy
  • Magazine: Large LMG Drum Magazine

Secondary Weapon

The Recurve Crossbow in Once Human
Once Human Recurve Crossbow

If you're playing solo, the Recurve Crossbow in Once Human is likely the best option you have. Not only does it apply The Bull's Eye on weakspot hits, but it also increases your Crit Rate against enemies marked by the crossbow itself. However, if you're playing with a group and someone also has a means of applying The Bull's Eye, we recommend using the S870 Sandstorm instead, as it deploys a Fortress Warfare field just by switching to the weapon.

Players who really want to keep shooting can opt to use another machine gun instead of the previous two. The MG4 Wrath of Hades refills one bullet to your other weapon every time it triggers Fast Gunner. Once the MG4 Predator runs out of bullets, swap to this one and shoot until your magazine is dry. Then, swap back to your Predator. Alternatively, just get another Predator.

Armor Set

Description of the Bastille set in Once Human
Once Human Bastille set description

The 3PC Bastille set gives players a 40% Weapon DMG buff when crouching still and another 10% Weapon DMG if they're above 70% HP. It's free damage that can be triggered very easily. The caveat here is you likely won't be able to take advantage of this 50% buff all the time, as the game punishes stationary playstyles. Still, you'll be able to get such a large damage bonus in DPS windows when bosses are stunned or distracted.

If you don't like the Bastille set, get the Lonewolf set in Once Human for the added Crit stats. You can even use the Renegade set if you want to build for Weakspot DMG. However, keep in mind that not all enemies have weakspots, and some have weakspots that are hard to hit. Stacking crit is a more convenient way of dealing damage, while stacking Weakspot DMG is often much stronger, but harder to put into practice depending on what you're fighting.

Oasis Vs Dust Mask

Dust Mask description in Once Human
Once Human Dust Mask description

The Oasis Mask increases the max Fast Gunner stacks you can have by 10, and it increases the Attack damage buff of each stack from 1% to 2%. This means you can have a total of 20 Fast Gunner stacks with a gold Blitzkrieg mod equipped, translating to +40% bonus damage and fire rate. Use this if you want to deal as much damage as possible in a short period of time.

Meanwhile, Dust Mask gives you a 50% chance to automatically reload 1 bullet in your magazine every time you trigger Fast Gunner. This won't increase your DPS, but it'll let you lay down the trigger for longer, resulting in more damage per magazine and less DPS downtime overall. Since the MG4 Predator deals more damage with the top half of its magazine, this mask will let you enjoy that buff for longer.

Covered Advance

As of writing, Final Territory may be bugged, as it doesn't appear to give any bonus stats after Fortress Warfare ends.

All these mods should be self-explanatory. They're all here to increase your damage output. Although, there are some parts here that could do with some clarification.

The build uses Momentum Up over the likes of Fateful Strike and Precision Rush because of the MG4 Predator's unique attribute, which makes it deal more damage with the top half of its magazine. Momentum Up's +10% fire rate buff lets you rip through enemies with that top-half damage buff more quickly. It also dampens the damage loss you get when the Predator dips below half ammo.

If you don't have a gold Shoot Out, then Shooting Blitz is a decent alternative. You get 5% less damage, but if you manage to get one with good attributes like bonus Crit or Weapon DMG, consider using that over a purple Shoot Out mod.

It's worth reiterating that while Weakspot DMG from mods like Precise Strike grants better DPS, opting for Crit stats is often better for the sake of convenience, especially since LMGs are inaccurate by default. In this build, treat Weakspot DMG as a nice bonus to have instead of something you absolutely must build around (though that's completely viable as well).

Once Human Fast Gunner Build Deviant And Food Buffs

When picking a Combat Deviant, the Lonewolf's Whisper that drops from Once Human's Shadow Hound boss is the best pick for a gun-based build. It increases your Weapon DMG while active, stacking on top of all the other Weapon DMG buffs you have going on.

As for food buffs, there are a few options:

  • Shattered Bread: +10 Weapon DMG
  • Stargazy Pie: +25% Crit DMG when your Energy is full
  • Assorted Canned Fruti: +25% Weakspot DMG when Sanity is above 80%

Unfortunately, there aren't many Cradle Override perks that directly affect Fast Gunner. Steady Hand is here to increase your Weakspot DMG, but that's about it. The rest are here for general damage and survivability boosts.
