    • Hi-NRG2 Plasma Lance - 2nd generation of the Hi-NRG. It boasts a higher rate of fire, reload speed, and ammo efficiency, at the cost of less powerful shots. Its shots also have a smaller blast radius, allowing for safer use in close - medium range engagements.
    • Hi-NRG3 Plasma Lance - A custom model commissioned by Belltower Associates. Its' projectile damage and splash radius have been dramatically increased, at the cost of less efficient energy consumption and slower rate of fire to prevent from overheating.
