The Energy Sword's plasma is held into a blade-like form with small magnetic field generators built into the handle mechanism. This technology is found in all the Covenant plasma weapons. In Halo: Combat Evolved, if the wielder drops the weapon, a fail-safe activates, deactivating the magnetic field without first dispensing the plasma, consuming the handle and destroying the weapon. In Halo 2, a similar fail safe is active when not wielding the weapon directly. The handle must be under pressure from the handler to be activated, so the weapon can be stored.
Note:Can only be used by Spartans
Type-25 Directed Energy Pistol
The Plasma Pistol, like the Plasma Rifle, is a directed energy weapon that fires bolts of superheated ionized gas (i.e. plasma) instead of traditional Human ballistic ammunition. This Covenant weapon is capable of quickly firing low-powered shots, or of charging a single high-powered blast which can rapidly deplete energy shielding. This high-powered shot makes the Plasma Pistol a formidable strategic weapon if used in concert with other infantry weapons. The Plasma Pistol is a standard-issue weapon for lower-ranking Covenant such as Grunts and Jackals
Type-25 Directed Energy Rifle
It is a common light weapon in the Covenant army, primarily wielded by Elites. The Plasma Rifle uses plasma technology instead of projectile ammunition, firing directed energy bolts. This means that the weapon draws from a power source to generate its energy bolts rather then firing individual metal projectiles like modern guns. The core power output of these projectiles is 100-150 Kv @ 2-3 dA, and the rate of fire is 420 to 600 rounds per minute. The Plasma Rifle is particularly effective against shielded bipedal opponents.
Type-33 Light Anti-Armor Weapon
The Fuel Rod Cannon is a Covenant heavy weapon. The Fuel Rod Cannon has no fail-safes (unlike the prior game's Fuel Rod Guns), allowing the player to pick up the weapon. It fires blobs of deadly radiation rounds that explode on impact with targets or surfaces. It is often wielded by Heretic Grunts. Unlike many Covenant weapons, the Fuel Rod Cannon fires ammunition in clips of 5. Up to 25 additional fuel rods can be carried for a total of 30 shots.
Type-33 Guided Munitions Launcher
The Needler is a highly unusual Covenant weapon in that it fires pink, translucent, crystalline projectiles. It is most often wielded by Unggoy (Grunts), and Yanme'e (Drones), but Sangheili (Elites) and Kig-Yar (Jackals) have also been seen utilizing this firearm. It's razor sharp crystalline projectiles are fired from this elaborately designed Covenant weapon; it is widely believed that they use heat or organic signatures to home in on targets. Although easily deflected by energy shields, the needles cause a chemical reaction in close proximity resulting in an explosive effect. After a number or needles have entered a hostile(Seven actually), they will shatter causing massive internal damage.
Type-50 Sniper Rifle System
The Beam Rifle is an extremely powerful weapon capable of sniping enemies from long ranges. A single headshot is enough to neutralize an enemy while a shot to the body will collapse an enemie's Shields. Unlike the Human Sniper Rifle, the Beam Rifle runs on a battery much like Plasma Pistols and Plasma Rifles do. These rifles are abundant in Halo 2, being used primarily by sniper Jackals. Their scope seems to be smartlinked, like the M6D Pistols, however it is unknown how members of the Covenant use the scope.
Type-51 Carbine
The Carbine is the Covenant equivalent of the UNSC BR55HB SR Battle Rifle and the BR55 Battle Rifle. It is a semi-automatic weapon that combines high accuracy with decent stopping power. It is used primarily for mid-range combat. Unlike most standard-issue Covenant weapons such as the Plasma Rifle, the Carbine does not run on a battery. Rather, it fires solid, radioactive projectiles from an 18-round cylindrical magazine, sometimes suggested as being analogous to a "stripper" style magazine.. It is sometimes carried by Brutes and Elites, though this is not usually their preferred weapon. In the hands of an enemy Brute or Elite, they can be deadly, allowing them to engage their enemies at mid range with deadly accuracy.
