M90 shotgun

The M90A CAWS Shotgun is a United Nations Space Command firearm. It is a model in the DTM Series of shotguns made by Weapon System Technologies.

UNSC Law Enforcement units are equipped with a similar weapon, the M90A Law Enforcement, which has a fixed stock and no pistol grip.

Introduction
The M90A Shotgun is the latest Model of the resident UNSC close combat weapon, and packs extreme stopping power at close ranges, and will kill almost any enemy in 1 hit at close ranges, it can also kill up to 3 Covenant Grunts with only 1 blast at close ranges. It is often wielded in urban conditions, where the close ranges are conducive to the shotgun's mode of operation. The shotgun also makes a perfect defensive weapon to fend off Covenant boarding parties inside starships.

The weapon's power lies in the great stopping power of a cloud of buckshot, which, while extremely powerful in close-quarter combat, is useless at long ranges. However, it should be noted that the shotgun user can engage enemies at medium ranges also.

Advantages
Since the shotgun fires 15 spreading pellets per shot, the combined force of each relatively weak pellet does a significant amount of damage. Its high damage potential (as much as a rocket in Halo 1 at close range) makes it effective against almost any Covenant unit (even the Hunter, if shot in its exposed back), but only if the player can get close enough to render the gun effective. In addition, this weapon is extremely effective against all forms of Flood at short and medium ranges, and is capable of eleminating Combat forms in 1 shot, and an army of infection forms with 1 shot also. The shotgun also reloads in a different manner than the rest of the weapons in Halo. Each round is put into the shotgun, one-by-one, so reloading all six shells at one time may take a while. However, the player may interrupt the reloading process at any time and fire with however many rounds are currently loaded into the weapon. Another popular way of firing the shotgun involves inserting a shell, firing, and then inserting another shell, etc. While this takes slightly longer, it has the advantage of always having shells chambered. Apart from that it is devastating in close combat, stronger than an Energy Sword swipe, but slightly weaker than the Energy Sword lunge.

Disadvantages
While highly effective at close range, Medium/Longe Range Weapon can render it useless if out in the open. And the time to reload can make fighting with a great deal of enemies difficult, especially without cover to hide behind.

Campaign Recommendations
If you see one of these, you better pick it up. It is totally effective against the Flood, and works great on levels like The Library. If you ever end up reloading, remember to hide behind something and avoid Elites and Infection Forms. You reload bullet by bullet, so it is best to use with a large amount of cover.

This weapon is an effective and deadly CQB weapon, but if the aimer point is not red, the bullets won't hit your target. conserve this ammo as much as you can, because it is considered by many to be the most effective weapon of all!

Multiplayer Recommendations
The shotgun's effectiveness in multiplayer games varies depending on the terrain; indoors and in tight spaces, the shotgun is unbeatable (equal to the Energy Sword). Many players carry the shotgun and a weapon that is very effective at Medium and above ranges such as the sniper rifle, Covenant Carbine, M6D, BR55 Battle Rifle, thus making for a more flexible arsenal. Continuous firing by using the magazine and loading one shell then firing does not affect the rate of fire significantly, prompting a few players to employ a tactic dubbed "shotgun sniping" as suppressive fire across medium-sized maps. On the Internet, many games are shotguns only, with most of these battles being set in the map Battle Creek (Level).There is move combo players commonly use with the shotgun:since the enemy players commonly are on the move when being advanced on by a foe with a "special" weapon like the sword, rocket launcher, shotgun or a vehicle, players with the shotgun can finish enemies off safe and quickly by shooting them at a decent close range then melee them the second after that gaurenteeing an instant kill.

Remember: 3 shots can kill an enemy with shields!

Multiplayer Medals (Halo 3)

 * Shotgun Spree Medal - Gun down 5 opponents in a row without dying.
 * Open Season Medal - Gun down 10 opponents in a row without dying.

Appearances/Differences between the M90 models

 * The Shotgun appeared in Halo 1. The weapon's model was the Mk I, and had very pronounced blue front and back sights. It may have fired a different kind of ammunition than its' Halo 2 counterpart, as the range of this model was much longer, and the damage was slightly higher. The M90 Mk 1 was pump action (as every other Shotgun Model), but the Player could hold the Fire Button for continous fire and pump (This cannot be done in Halo 2 & 3). The player could carry a very large amount of shotgun shells at one time, a total of 72 shells.


 * It also appeared in Halo 2. This model was the Mk II, and although it did more or less the same amount of damage, its range was greatly reduced. It also featured a green Ironsight & a decreased ammo capacity, with the player only able to carry a total of 48 shells at a time.


 * The newest model, The M90A Close Assault Weapon System (CAWS) will appear in Halo 3, as it did in the Beta. The original Blue Ironsights will return, and it now has a longer range, but half the capacity of the magazine capacity than the Halo & Halo 2 Models. The Player can carry up to a total of 54 Shells, but this might change.


 * The DTM Series of the M90A shotgun is available in 20 gauge, and 10 gauge for the civilian market. The 8 gauge is only sold to law enforcement (such as the WST DTM/LE model) and military agencies. The DTM series has not appeared in game yet, but most likely won't be featured in Halo 3.

Ammo
The M90 Shotgun uses the Soellkraft 8 Gauge magnum shotgun Shell. This is an incredibly large round not used by most modern militaries, but recoil has been said to be relatively low, so technology must have improved in the future. The shells have a hippo on the side in Halo: Combat Evolved.

Influence
The mechanical design of the M90 shotgun is loosely based on the South African Neostead shotgun which features dual six-round top-loaded magazines. The weapon features two integral tube magazines with a total capacity of twelve rounds (6+6+1) and ambidextrous bottom ejecting shells. It is chambered for standard 12-Gauge 2.75-inch cartridges. The aesthetic design is a composite of multiple pump-action designs, most notably the mossberg 500.
