From Halopedia, the Halo wiki
The Loathsome Thing is a special Z-180 Close Combat Rifle/Asymmetric Engagement Mitigator.
The Loathsome Thing is a named variant of the Z-180 CCR/AEM, with upgrades including a 10-round magazine, a faster rate of fire, faster reloading speed between projectiles, and a slightly higher damage output. Reusing the standard Scattershot's model, the Loathsome Thing is decorated with additional orange stripes covering the weapon, particularly around the front barrel area and the rest of the weapon's main body.
In October 2558, two copies of the weapon were left in an area on Kamchatka that Fireteam Osiris passed through on their mission to recover Catherine Halsey from Jul 'Mdama and his Covenant forces. The weapon was later integrated into War Games simulations for use by Spartan-IVs aboard the UNSC Infinity.
Halo 5: Guardians
The Loathsome Thing appears as an Ultra Rare Level 4 REQ that grants 150 REQ Points when sold. It has a faster rate of fire and slightly higher damage output compared to the normal Scattershot, as well as a 10-round magazine. These improvements make the Loathsome Thing a powerful weapon against multiple enemies up close, as it gives the enemies less time to react, although it retains its overall range from the Scattershot: 13.73 m (45.05 ft) in hipfire, 18.13 m (59.48 ft) with Smart-Link, and a maximum projectile range of 39.43 m (129.36 ft).
