"Assembled with Russian know-how from the scraps of war and inter-dimensional combat, the Hellfire flamethrower has incinerated legions of filthy hell-pigs."
At Level 1, the Hellfire functions similarly to the Purifier, acting as a Flamethrower that can damage any enemies. After each kill with the flamethrower, the player also gains additional Armor. At Level 2, the Blast Vent ability is unlocked, allowing the player to release a burst of pressurized air, sending enemies flying. At Level 3, the Infernal Tempest ability is unlocked, allowing the player to create a tornado of flames that wipe out any enemies in its path.
