From Halopedia, the Halo wiki
The Z-180 Close Combat Rifle/Asymmetric Engagement Mitigator (Z-180 CCR/AEM), commonly known as the Scattershot, is a Forerunner energy channel weapon that was originally used by Builder Security forces. It is commonly carried by Promethean Knight Battlewagons.
The Scattershot gained popular use by Builder Security who used it to engage the Flood during large scale evacuations of Forerunner planets. Effectively an exotic analogue to a human shotgun, the Scattershot was first used as a close-range defensive weapon toward the end of the Forerunner-Flood war. The Scattershot is extremely dangerous in relatively close quarters, and fires multiple individual projectiles, though its most remarkable attribute is that its rounds can ricochet off surfaces. As a weapon created to combat the Flood and prevent them from reusing corpses, it will disintegrate its targets if enough of the projectiles hit them at the same time.
The weapon bears the hallmarks of Forerunner design: highly angular and metallic. It appears to be held together at least partly by energy fields, as indicated by its self-assembly process and floating sights. Orange highlights can be seen while the weapon is self-assembling and throughout the casing once assembly is complete; these highlights grow brighter when the weapon is fired. The weapon receives five energy cells from a breach-loaded compartment. The Scattershot was manufactured and developed by Ferrarius Assembler Vats.
In Halo 4, the Scattershot fills a role as a close-quarters power weapon, similar to the UNSC's M45D shotgun. The Scattershot differentiates with a faster rate of fire but a lower lethal range (though its effective range exceeds the shotgun's), and smaller magazine size and lower total ammunition carried.
In Infinity Slayer the Scattershot is a relatively common Ordnance drop weapon. It also spawns at the start of match on several maps, such as Adrift, Abandon, and Haven. The weapon is best used in engagements where at extremely close range, such as the enclosed hallways of Adrift or out of the lifts on Abandon.
In object-based matches, the Scattershot is an excellent defensive weapon for just about any gametype. Anyone charging your hill or attempting to take your flag should be met with the brutal rebuke of your hard-light projectiles. On the offensive, having one is a great way to clear said hill or flag zone of defenders, and taking down the Oddball carrier.
In Dominion matches, although the Scattershot is a relatively rare ordnance drop and does not appear at all in Lockdown, it is still very useful, and, unsurprisingly, an excellent weapon for defending bases.
Halo 5: Guardians
In Halo 5: Guardians the weapon performs more or less identically to its predecessor, with some major differences. First, the weapon now fires consistently, with the shots of the weapon forming a spread-X pattern, which is then constricted under smart scope's use, a stark difference to the Halo 4 rendition's inconsistent output. In addition, bolts will track slightly, similar to other hardlight weapons in Halo 5: Guardians, if bounced off a hard surface. This makes the Scattershot a brutal tool for controlling a point in Strongholds, protecting a flag in CTF, or cleaning out an Armory in Warzone. It should not, however, be utilized for long-range engagements past 10.3 meters (34 ft), as its range increase is not that dramatic.
Warzone variants include the Loathsome Thing, which features increased magazine size of 10 rounds, more damage, a faster reload time, and a higher rate of fire, and the Didact's Signet, which has higher projectile tracking on ricochets and increased range, including the ability to instantly kill targets up to 21 meters (69 ft) away when scoped in.
In Halo: Spartan Strike, the weapon can ricochet and has double the range of the M45D shotgun. When fired, it spreads six projectiles that can bounce off walls as long as it is inside the range of fire.
