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 or heavy energy cells. 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.
