Known as either a Hellgun or Hot-shot Lasgun, these high-energy weapons are more potent and destructive than common Lasguns, drawing on external energy sources for a more penetrative shot, but also more complex, requiring reinforced barrels, thermal-cooling cells and gyro-stabilized power packs. A substantial backpack power source allows the weapon to be fired in both semi-automatic and rapid-fire modes. While the backpack power source is not quite as powerful as the Hotshot Laser Power Pack used in Long-Las sniper rifles it does produce an intense shot which, while still comparable to one from a normal lasgun, has far superior penetrative power.
