Bullets are so last year. Instead, why not incinerate your enemies from the inside out with a highly experimental anti-matter-powered gun firing supercharged plasma bolts? What's the worst that could happen? (If you find out, please report to R&D)


The Experimental Plasma Charger, shortened to EPC, is an unlockable secondary weapon used by the Driller. The EPC is capable of shooting supercharged bolts of plasma, which deals a high amount of damage to enemies.
The Experimental Plasma Charger can fire small, round bullets of plasma and a larger ball of charged up plasma which explodes on contact, dealing large amounts of area damage, at a higher ammo consumption. The shot can be charged up by holding the fire button. Like the Powered Minigun, firing the weapon for too long or firing a charged shot, will cause it to overheat and become inoperable for a short duration.

Unique Modifications

Flying Nightmare

Icon Upgrade Special.png

Flying Nightmare applies an AoE sphere around the Experimental Plasma Charger's charged shots that travels along as the charged shot flies; it deals 100 damage to each enemy that it touches. However, the damage of Flying Nightmare is reduced because of armor reduction and/or another hidden modifier.

Thin Containment Field

Icon Upgrade Special.png

Unstable Containment Field causes the charged shots of the Experimental Plasma Charger to explode, carving any terrain and dealing 240 Fire damage to nearby creatures, when hit with an high-impact weapon. Player's can either shoot the projectile, use the Driller's Impact Axes, or have another player shoot at the charged shot with a projectile weapon.

Bouncy Plasma

Icon Upgrade Ricoshet.png

Bouncy Plasma will cause every regular bullet that is shot out of the Experimental Plasma Charger to ricochet off of enemies and objects. This mod applies a unique attribute that causes each regular shot to pierce armor.

By changing how the plasma is layered within the charged projectile a slow and persistent discharge can be achieved upon impact. However this does reduce the instant damage done.
