Plasma rifle (Fallout)

The Winchester P94 plasma rifle is an energy weapon in Fallout and Fallout 2.

Background
The P94 is a bulky, industrial-grade energy caster powered by microfusion cells. The superheated plasma bolt forms in a special chamber, then sent down a superconducting barrel and stabilized by electromagnetic claws upon exiting it.

Variants
A superior version of this weapon exists, with a hotwired plasma bolt chamber, called the turbo plasma rifle.

Locations
Unlike the laser rifle, the plasma rifle is rare in Fallout. They are mostly found in the Military Base and Cathedral. You can also kill certain super mutants or get them from the Gun Runners. One example also exists in the secure testing labs of The Glow.

Behind the scenes
Elder Owyn Lyons mentions the P94 plasma rifle when in dialogue in Fallout 3, but it is not in the actual game, being replaced by the urban plasma rifle.
