Summary
This is a Covenant directed energy weapon. It is capable of either semi-automatic or automatic fire. Continuous rapid fire overheats the weapon - this in turn depletes the weapon's power core. We currently do not understand how to replace or recharge a power core. This weapon has a heat gauge on the side, pay close attention to it to lower chances of overheating.
This weapon uses a smaller version of the plasma technology used in the Covenant's main capital ships. By using a small magnetic field generator, the plasma is forced forward after discharge in small bolts.
Note: This weapon will deplete its energy source as you use it. It is wise to replace it as often as possible.
