The M6 Spartan Laser is a shoulder-mounted direct energy weapon used by the UNSC. It fires an extremely powerful red laser, capable of destorying vehicles and infantry with one accurate strike. When the trigger is pulled, a targeting dot is projected. The laser will then charge for three seconds before firing its powerful and destructive burst.

The M41 Rocket Launcher, alternatively called the "Spanker" or "Jackhammer", is a heavy ordinance weapon of the UNSC arsenal. The M41 sports a 2x scope and can fire rockets over long distances with devestating accuracy.

The SRS99D Sniper Rifle is the primary long-range rifle used by UNSC forces. It is, alongisde its Covenant counterpart the Particle Beam Rifle, the most accurate, and arguably themost powerful infantry-sized weapon in both arsenals. The rifle's only drawbacks are its cumbersome reload and its bulky, thus necessariliy scarce, ammunition under typical battlefield circumstances.

The BR55 Battle Rifle is a UNSC gas operated projectile weapon. It firest a larger caliber bullet than an assault rifle, giving more power but also more recoil. The BR55 is restricted to three-round bursts of fire.

The rifle is an excellent all-around weapon. Its biggest problem lies in its magazine capacity - allowing only 12 shots before reloading.

The M90 Shotgun is the resident UNSC close combat weapon. Because of its extreme stopping power, the M90 is often wielded in tight or confined conditions, where the close ranges are conducive to the shotgun's mode of operation. It is, however, a very large and heavy weapon.

The MA5C is a fully automatic, air-cooled, gas-operated, short-to-mid range weapon. The weapon houses an onboard electronics suite, including a screen indicating rounds left in the magazine. The weapon's power is described as falling somewhere between the MA5B Assault Rifle, and the BR55 Battle Rifle.

The SMG is a UNSC issued, gas operated projectile weapon capable of continuous fire. The impulse-to-mass ratio of this weapon necessitates that the user constantly readjust aim during sustained fire. The SMG's main advantage is its high rate of fire.

The M6G Pistol is a typical UNSC sidearm. It fires high explosive bullets with a relatively fast rate of fire and good accuracy. While hardly a sniping weapon, in the hands of a trained marksman the M6G can remain very accurate over long distances.

Currently structured under the UNSC (a military command government), Humans find themselves damaged after years of fighting against the Covenant. Primarily a peaceful, exploratory species, Humans have attempted several diplomatic outreaches in this conflict, all ignored. Human occupied worlds have been destroyed and the current population has dwindled to almost nothing. Earth is currently being occupied by a Covenant archaeological/military force.

The battle-hardened Sergeant is the longtime cohort of the Master Chief. No other human knows the Master Chief as well as this capable and brilliant marine. Johnson is that most singular of soldiers; a professional who's never more at home than in the thick of battle, and a loyal fearless warrior who will do anything for his men, and his homeworld.

Cortana is the highly advanced AI (UNSC's most sophisticated) at the heart of the Pillar of Autumn spacecraft. Her design allows her to be uploaded into an appropriately configured battle suit, or to represent herself in holographic form.

After helping destroy the first Halo by piggybacking on the Master Chief's armor, she formed a closer bond with him - but that bond was wrenched apart by events on Delta Halo. Her last known location was aboard the Flood-infested Covenant capital ship, High Charity, in the thrall of the Flood hive intelligence - the Gravemind.

Master Chief (real name John-117) is the last of the Spartan II warriors - an elite group of genetically superior, highly trained super-soldiers.

Spartan 117 is expert in all weapon and combat systems. He can run faster, jump higher and hit harder than any normal human. He is the perfect weapon, honed by years of battlefield experience and possessing a natural talent for war, unmatched by anyone left alive. He is our last and best hope.
