The Type-25 Directed Energy Pistol, also known as the Plasma Pistol, is a Covenant infantry firearm commonly wielded by the smaller Covenant member species, such as the Unggoy, Kig-Yar, and the Yanme'e. The Plasma Pistol is a Covenant Directed Energy Weapon reverse engineered from Forerunner technology that uses a weaponized variant of the fourth stage of matter Plasma to serve as a worthy weapon on the battlefield. The weapon is powered by a battery cell. The weapon has a power output of 100–150 kV at 0.2–0.3 A (20–45 kW), but when overcharged, the power output is 1.5 MV at 0.2–0.3 A (300–450 kW).The Type-25 DEP is a semi-automatic weapon using a single collimator design that gives the weapon its smooth and aerodynamic, claw-like appearance. The Type-25 DEPs functionality is straight forward; the rear section of the pistol has a holographic display indicating weapon temperature during use—in the center of the holographic display is a small red pad known as the Type-25 DEPs safety and activation mechanism. It is used by the Alliance of Nations, Axis of Empires and the Coalition of Independent States.
