Plasma Rifles
Originally these were standard hydrogen plasma rifles, shooting jets of ionized hydrogen in a slightly- more- sophisticated variant on a gas- fueled flamethrower, and those are still available to agents who want them. But the danger of the hydrogen fuel igniting in what more than one agent has termed ‘a Hindenberg’ was high, especially in combat conditions.
Recently Alpha One Agent Omega, a scientist in her own right, applied her inventiveness to this perennial wallflower of the armory, and with the help of Weapons Lab chief Madrid, modified the rifles, replacing the hydrogen tanks with helium, and adapting the weapon to run on the standardized power packs used in other weapons. Further miniaturization was brought about when Weapons Design chief Madrid substituted pelletized fuel.
