Z-180 Scattershot

The Z-180 Close Combat Rifle/Asymmetric Engagement Mitigator, commonly known as the Scattershot, is a weapon of Forerunner origin first encountered in Halo 4 on the shield world Requiem.

Overview
The scattershot is a weapon used by Forerunner Promethean Knights encountered on Requiem. This weapon seems to lend itself to close-range combat due to both its low clip size, five rounds, and its wide spread as indicated by the weapon's reticle in the MJOLNIR's HUD.

Design details
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.
