This plasma rifle is a lightweight urban warfare weapon created as part of a desire to replace the aging WinchesterP94 "Plasma Caster" design. This design was produced and fielded in number prior to the Great War of October 23, 2077. This however was not the end of the design nor manufacture of this weapon platform. Prior to the nuclear Armageddon, REPCONN Aerospace (as a subsidiary of RobCo Industries) would successfully develop an improvement from their spaceflight research, with significantly advanced factions tinkering with the design post Armageddon.
The tuned plasma rifle is a modified plasma caster featured in Fallout Shelter that fires super-heated bolts of plasma, using microfusion cells to heat and fire the plasma. Dealing 17 minimum damage per attack, it has the highest damage output for an energy rifle in the game.
