Other Weapons

Assault Cannon

These weapons are mounted on Hunters, and fire devastating beams of green ignited fuel like the normal Fuel Rod Cannon, and do tremendous damage. In Halo: CE Hunters have a version that is more like a banshee bomb, not a beam. In Halo 2 however, the Hunters weapon is upgraded to Assault Cannons that shoot beams. In Halo 3 the "beam" is actually more like a hose, and resembles a miniature Scarab Beam. The assault cannon can be weilded with deadly power.

Gravity Cannon

Similar to the modified Assault Cannons integrated into the Hunters' armor, the gravity cannon fires/projects a continuous pair of reddish-gold beams unlike the green hunters' conterpart weapon. this beam also goes on for a few seconds longer that of the hunter. Not much more is known about this weapon, except that it has only been used by Prophets, mounted into the throne-chair and can fully reduce health and shields within a few seconds of continuous fire.

Energy Garrote

One of the Elites' special stealth weapons is the energy garrote. It is a small, two-piece cylinder that splits apart in the middle. A green energy arc appears between the two cylinders and is used to choke and burn an enemy quietly from behind. This can be considered a form of assassination.

Energy Cutlass

Jackal privateers were known to employ short, crystalline blades as a melee weapon. It was also used by other various Covenant forces. The pink, glass-like blade would explode when jammed into a target, much like the ammunition of Needlers, and was used in a manner similar to a machete. One could throw the cutlass into a target, and it would explode moments later.

Plasma Mortar

These stationary plasma mortars are the heavy siege weapons that the Covenant sometimes employ during invasions. Plasma mortar launchers are also equipped on Wraith tanks. The plasma mortar itself will take the form of a blue ball, arcing upwards before slowly plummeting downwards. When it hits something, it detonates, doing a large amount of damage. It is not currently known how strong the mortar shots are in comparison to human tank shells, but they are known to be very similar in the damage they can do.

Energy Tether

Covenant soldiers have been known to use energy rope-like tethers to climb and descend steep surfaces.

Covenant Bomb

The Covenant employ large anti-matter bombs to destroy large targets and structures. The bomb is 3.21 meters long and covered in large "spines" that are presumably used to help keep the bomb lodged in the target long enough for it to explode and possibly make it hard to move. It is known by Bungie as "The Giant Covenant Space Pickle."

Energy Stave

This stave is mainly wielded by Honor Guard Elites. It glows a reddish-orange color and appears to be purely ceremonial in nature, as no Honor Guard has ever been seen actually fighting with it (Although Elite Minors used the weapon in the Halo Wars cutscene "Monsters"). There has been speculation about the possibility of the blades on these weapons being energy based like the energy sword; however, as mentioned before, the pike has never been observed in combat, and so these theories remain unproved.
