The Plasma Gun is a very powerful gun found by the ex-officer Kal Wardin in N.O.V.A . When charged it will produce large orbs of plasma that can hurt both the Player and Xeno troops alike. If shot when the weapon is not fully charged, it will produce smaller orbs of energy that have reduced damage and blast radius.
The most striking feature of the weapon is that it does not require ammunition, hence eliminating most of the functionality of the pistol.
