Plasma rifle

Plasma rifles are energy based weapons that appear in Fallout, Fallout 2, Fallout Tactics, Fallout: Brotherhood of Steel, Fallout 3, Fallout: New Vegas, Fallout Shelter, and Fallout 4.

Background
 Plasma rifles or plasma casters are high tech weapons firing superheated bolts of plasma, powered by either microfusion cells, heavy energy cells, plasma cartridges, or plasma cores which find numerous applications in military and industrial fields. The bolts form into toroids in the plasma chamber, which are then sent down a superconducting barrel. However, the plasma bolt chamber can be hotwired in order to accelerate the bolt formation process, effectively turbocharging the rifle. The primary damage mechanism of plasma rifles is thermal transfer, causing serious burns to soft targets and melting hard ones. In extreme cases, the plasma can cause spontaneous dissolution of the target, including separation of soft tissues from hard ones or wholesale molecular destabilization that turns the target into a viscous green fluid.

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. An additional model known as the Gatling plasma, made in a similar fashion to the Gatling laser, would also come into use.

Winchester P94


 The Winchester Model P94 is a bulky, industrial-grade energy caster, firing superheated bolts of plasma down a superconducting barrel. In an interview for Future Weapons Today, United States Army Colonel Moretti slammed the design, likely for being bulky and outdated. This would lead to corporations like REPCONN Aerospace and Poseidon Energy undertaking projects intended to replace the P94.

In the military version, the company has downsized the weapon and revamped its design, making it a more portable energy rifle, complete with a stock, pistol grip and carry handle.

Plasma rifle


This plasma rifle is a lightweight urban warfare weapon created as part of a desire to replace the aging Winchester P94 "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. 

This rifle uses a microfusion cell as its power source and draws plasma from a separate cartridge. When depressing the trigger, a plasma toroid is produced that can remain stable under normal atmospheric conditions. This toroid is then ejected down a superconducting barrel against a given target. The rifles are highly modifiable, able to be converted into a pistol with ease and potentially turned into a designated sniper rifle, flamethrower, scattergun, and even an automatic rifle by simply swapping out the barrels.

Q-35 matter modulator


 Also known as the V.35 Quantum plasma modulation matter injection rifle, the Q-35 matter modulator was created by REPCONN Aerospace engineers as part of the Quantum Plasma Modulation Matter Injection Rifle project, a research program overseen by Colonel Moretti of the United States Army, who was looking for a replacement for the aging plasma rifle designs, especially the Winchester P94.

The prototype, whose three previous versions (V.32, V.33, V.34) had failed, was created by a team of engineers under the leadership of Senior Staff Engineer Xuan Duong, using design specifications stolen from Poseidon Energy for the canceled plasma rifle initiative, Project SEMELE, in conjunction with designs from their own plasma engine, the failed quantum matter modulator of the Z43-521P rocket. Poseidon data allowed the REPCONN team to rectify issues with matter inversion by using a polarized quantum spin, simultaneously solving the issues with matter conversion in the Heisenberg compensation field, enabling the creation of the first prototype of a new line of plasma weapons.

With the data from the SEMELE project, REPCONN was finally able to create a functional prototype. While prototype materials make it unsuitable for prolonged field use, the Q-35 has a longer refire rate on average, but a more consistent delay between shots, an increase in active bolt charge time, increased accuracy and a 30% increase in bolt energy.

When the prototype was completed, individuals suspected to be working for Poseidon Energy conspired with REPCONN's CFO, Julia Masters, to intercept and secure the prototype while it was in transit to the Department of Defense. 

Multiplas rifle


 The multiplas rifle (a portmanteau of "multiple" and "plasma") is based on the urban plasma rifle design. It is a sort of "plasma shotgun," firing three rounds of plasma in a volley, at the cost of a massive drain on the microfusion cell.

Electric plasma rifle


 The electric plasma rifle only appears in the city of Los and the Secret Vault. It's to be manufactured using technology contained in the Secret Vault. It's equipped by the most important ghouls of the Church of the Lost and some super mutants of Attis' army.

Turbo electric plasma rifle


 The turbo electric plasma rifle is an upgraded version of the electric plasma rifle and is only found in the Secret Vault. It's to be manufactured using technology contained in the Secret Vault. It's equipped by the most important super mutants of Attis' army and by the champion of the Gladiator Pit in Los, the wasteland stranger.
