The Type-25 Directed Energy Pistol (Type-25 DEP), also known as the plasma pistol, is a Covenant infantry firearm, carried commonly by the smaller species, such as the Unggoy, Kig-Yar, and the Yanme’e, but is occasionally used by larger species such as the Sangheili and Jiralhanae; as such it is the most commonly encountered Covenant energy weapon. While weak on its own, the plasma pistol has a wide variety of functions and becomes deadly in large numbers.
(Preferably the Halo: Reach or Halo 3 Version)
