Plasma rifles or plasma casters are high-tech weapons which find numerous applications in military and industrial fields. They fire superheated bolts of plasma powered by either microfusion cells,heavy energy cells or Plasma cartridges. The bolt forms in a special chamber, which is then sent down a superconducting barrel, propelled by, and in some models stabilized by electromagnetic claws upon exiting it.
Initially, the weapon was a bulky, industrial plasma caster, manufactured by Winchester Arms; while it performed admirably, it was expensive and required specialized training to use. However, later developments for the US Army would lead to a more compact design that was cheaper to produce and easier to train for, perfectly suited for urban warfare.
Regardless, all types of plasma weapons have a common feature: when a Critical Hit is delivered, they can literally melt down enemies. While most industrial casters aren't powerful enough to dissolve bones too, subsequent models have no problem converting the target into a puddle of goo.
This plasma rifle is a lightweight urban warfare weapon created by REPCONN Aerospace for the US Army based on engine parts from the failed Z43-521P - "Green Bean" plasma-powered rocket. Like the AER9 laser rifle, it uses a microfusion cell as its power supply. It taps into the cell, essentially a small fusion reactor, to produce a toroid of plasma that is ejected down a superconducting barrel. In contrast to the Winchester P94, it does not have the electromagnetic claws.
Compared to its Fallout 3counterpart, this plasma rifle has a much lower damage-per-second rating with only a slight improvement in damage. Factoring in the transition from the Damage Resistance system to the Damage Threshold system, the plasma rifle is vastly underpowered compared to its Fallout 3 iteration.
Unlike the plasma rifle in Fallout 3, this plasma rifle uses 2 microfusion cells per shot.
Powder Ganger members in the various farmsteads south of Vegas and near Vault 19 may carry plasma rifles or laser rifles.
REPCONN headquarters - one can be found on the northeastern side of the building, behind a couple of average locked doors, and in a small room with a lot of microfusion cells and three ammunition boxes.
