M90 shotgun

Template:Weapon Infobox The M90 Close Assault Weapon System (CAWS), also known as the M90 Close Assault Shotgun, M90 assault shotgun, or simply the M90, is a pump-action shotgun in service with UNSC. It is a military variant of the prolific DTM series of shotguns from Weapon Systems Technologies.

Overview

Design

Alternate views of the M90

The M90 is a pump-action shotgun, chambered in the extremely powerful 8-gauge magnum shell, and feeding from a 12-round, dual-tubular, non-detachable magazine. It is designed as a more practical and cost-effective recreation of Misriah Armory’s M45E Tactical Shotgun, though in UNSC service it is considered to be functionally identical. The magazine of the weapon is prominently positioned above the barrel, with the weapon’s glowing iron sights mounted atop it and the receiver located just behind, facing upwards, roughly in-line with the trigger. A flashlight is integrated into the weapon’s forend, which also features a prominent reddish button.

Functionality

As is typical of human firearms, in order to discharge the weapon, the trigger positioned at the top of the pistol grip must be depressed. Once the chambered round is fired, to fire again, the forend of the weapon (which serves as the weapon's foregrip) is slid back across the weapon’s underside towards the user’s shoulder, retracting the bolt and removing the spent shell from the firing chamber. If the weapon is loaded with standard 8-gauge magnum ammunition, the weapon's firing will take the form of a spray of pellets, referred to as "buckshot", which are quite powerful at close range but lose damage efficiency as the spray disperses. When the forend is fully retracted, the spent shell will have been ejected, and the way will have been cleared for the elevator to position a new round for the bolt to carry into the chamber when the slide is once again pushed forward. Once the weapon’s magazine is expended, new rounds must be inserted into the receiver to continue firing. At any time, with the action action closed, it is possible to top up the magazine with additional ammunition.

Depictions

The depiction of the M90 from Halo: Combat Evolved.

There are two primary depictions of the M90 CAWS. The first depiction is the original seen in Halo: Combat Evolved. The more recent depiction, however, is that seen in Halo 2, Halo 2: Anniversary campaign and Halo 2: Anniversary multiplayer. In the Halo: Combat Evolved depiction, the weapon features a smooth magazine with a chrome finish, and the iron sights glow blue. In Halo 2 and Halo 2: Anniversary, the magazine of the weapon has a dull grey finish with ribbed indents, and the iron sights glow green. In Halo 2: Anniversary multiplayer, the magazine retains its ribbed design but with a glossy black finish. In Halo: Combat Evolved, but not successive depictions, when the weapon is reloaded after being completely emptied, the weapon’s action is worked to chamber the first round.

Performance

The M90 is a devastating weapon in close, confined environments, with a loud report and strong recoil. The spray of pellets from the weapon mean that at slightly longer ranges, it can be used to hit clusters of targets simultaneously, but also makes the weapon inefficient at extended ranges due to the low ratio of shot which hits the target to the amount of shot fired.

Trivia

• In Halo: Combat Evolved, the M90 shotgun shares its reticule with the then-PC-exclusive flamethrower.
• In the second issue of Halo: Fall of Reach - Boot Camp, the captain of the UNSC Dartmouth retrieves several shotguns from a cryo chamber. In the first two panels, the shotguns appear to be M45s, though they resemble M90s in subsequent panels.
• In Halo 2: Anniversary, if the player uses Active Camouflage while the M90 is equipped, the shells will be the only objects still visible. This could be because the shells are technically not attached to the shotgun (like the magazines in other weapons) but rather held inside the weapon until ignited and fired. This is best seen when playing as the Arbiter.
• In Halo: Combat Evolved, the shotgun is the most effective weapon in the game against most Flood forms. A single shot is capable of killing Flood combat forms and Flood carrier forms and works best when paired with a weapon with a high-rate of fire such as an MA5B assault rifle to deal with Flood infection forms. The shotgun is still effective in later games, but not to such a degree as, starting in Halo 2, infection forms can revive deceased combat forms unless the body is destroyed. Halo: Combat Evolved lacked this resuscitation ability for the Flood.
