Penetrator

The Penetrator (originally named the SMG-9000 in the Preview Campaign) is a submachine gun in Ion Fury. As of the demo variant with the Heskel's House of Horrors mission, this weapon fires incendiary rounds, and can be dual-wielded if a second Penetrator is obtained. The player can switch to a single-wielded weapon with the alternate fire button.

Most weaker, semi-cybernetic or undead humanoid enemies, have a chance of being set on fire when hit and they will continue to burn until dead. Among them only Greater Cultists appear to be resistant against afterburn damage naturally and will try retaliate before fire succumbs them finally. Cultists, and Liberators gain resistance against afterburn at high difficulties. Only Mutant types become completely incapacitated when lit on fire at any difficulty but shots must be aimed precisely at their head else it will be absorbed by their armor. Small frame enemies such as Mechsects and Drones won't pose much of a problem at the face of small bursts but such great firepower shouldn't be wasted against them. While incendiary flechettes may sound weak against fully cybernetic enemies immune to its ignition, Deacons and Skinjobs can't withstand much against focused bursts on their head.

Despite looking only semi-cybernetic with limb augments, Wendigos appear to have highly resistant against Penetrator flechettes; they're capable of absorbing a full mags of flechettes emptied on them and stay alive at high difficulties. Another resistant enemy be the Diopede units as expected but they can be dispatched by using less than a single magazine unlike Wendigo.
