For the Killing Floor 2 Firebug, click here.

The Firebug is one of the perks in Killing Floor. They utilize fire against the zeds.

They level up by dealing fire damage. You do not currently have to be playing as a Firebug to level it up, as long as you are dealing fire damage it will count.

Once they reach level 3, their default grenade will be automatically replaced with an Incendiary Grenade. Additionally, when a Firebug uses a MAC-10 it has the added benefit of incendiary ammo to set zeds on fire.

Upon reaching level 5, Firebugs become completely immune to fire, nullifying the attacks of the Husk.
