Killing Floor 3is finally here. The third installment in the decades-old series brings a lot of recognizable faces back, including Firebug, the franchise’s dedicated pyromaniac.
In this game, her flaming skills and weapons are the cream of the crop as she sports some of the heaviest-hitting, fun-inducing, Zed-slaughtering guns out there. With such a variety of weaponry in the game overall, it might be challenging to know what the best loadouts, passives, and skills are. So, here is our best Firebug build inKF3.

The best Firebug build in KF3
Loadout
Every Perk inKilling Floor 3has a primary weapon and a sidearm by default, though they can carry two primaries during any given match. Each gun can be fitted with various attachments that can fundamentally change how it functions, from swapping out its Afflictions (damage types) to improving accuracy and providing team-wide buffs. Here are my picks for Firebug’s loadout:
Firebug’s primaries are many, but these two are the best to pair up in any given run. Dragon’s Breath is bar none the best gun in the game and will solo carry you through the toughest of difficulties, whereas Vulcan TA is a fantastic AOE gun to take with you against massive waves of enemies and bosses, especially smaller ones that you do not want to waste a Dragon’s Breath shot on.

The Pyre .357 is the only sidearm available to Firebug at the moment, but it’s by no means a bad pistol. With the attachments above, you’ll have maximum Heat Damage output, high on-hit damage, and solid handling that’ll stop the gun from flinching too much all the time.
Skills
Like other Perks, Firebug has three skill trees, each tied to a particular category. Here are our picks:
This selection of skills will ensure that you dish out maximum Heat damage, induce as much Panic into Zeds as possible, and heal at the same time. With this build, I have prioritized AOE, direct and indirect Heat Damage, creating massive and high DPS ground fires, and granting you passive bonuses that’ll ensure you’re never vulnerable or near death.
