The Mastiff Shotgun, or Mastiff, is a semi-automatic shotgun that utilizes Mythic Shotgun Shells.svg Mythic Shotgun Shells. It fires 8 pellets in the shape of a horizontal line, which decreases in width while aiming down the sights, reducing the spread and thus increasing accuracy.

Being a Supply Drop Weapon, it can only be found in Care Packages, and cannot equip foreign ammo. It comes pre-equipped with 28 backup ammo, a Shotgun Bolt.svg Shotgun Bolt, a 1x Digital Threat.svg 1x Digital Threat optic, and Dual Shell.svg Dual Shell.

  1. Shotgun damage is calculated per pellet.
    Correct: 11 dmg/pellet x 1.25 = 13.75 dmg/pellet ≈ 14 dmg/pellet, resulting in 112 damage total.
    Incorrect: 88 dmg x 1.25 = 110 dmg.
  • Fortified head shot damages may vary ±8. This is due to uncertainty over whether Fortified reduces non rounded or rounded damage numbers. This difference is negligible on non pellet based weapons.

The M1901 Mastiff Combat Shotgun was developed specifically for low-gravity close-quarters engagements. The kinetic energy produced when fired in low-gravity can severely unbalance its user with massive recoil, so the engineers at Lastimosa Armory incorporated a muzzle velocity dampening system which mitigates that energy and greatly reduces recoil.

Intended for low to zero gravity ship boarding and clearing operations, the Mastiff gained notoriety throughout The Frontier as a reliable and devastating combat shotgun. Shells can be fed through the under-mounted magazine or with the optional drum magazine upgrade. Troops from the IMC's 401st often refer to it as the "Mobile Claymore" as its high rate of fire proved to be devastating.[1]


There are a total of 63 skins for the Mastiff Shotgun; 11 Legendary, 6 Epic, 30 Rare, and 16 Common.

  1. Introduced in the Fuse Launch Bundle.



  • According to Bangalore, the Mastiff fires incendiary rounds.
  • Mad Maggie has a unique animation and voice line when picking up the Mastiff.
  • The Mastiff is the first weapon that got placed inside Care Packages more than once.
  • The Mastiff is one of the two guns in the game to reload one bullet at a time, the other being the 30-30 Repeater.
  • The Mastiff was named after Respawn's IT Manager, Roni Papouban's, dog.[1]
  • Dual Shell.svg Dual Shell doesn't actually chamber two shells into the Mastiff, it simply increases the number of rounds loaded by 2 whenever a shell is inserted.
  • The fire mode selector seen on the Warp Zone, The Pest Controller, Legend Tokens Final Boss, Legend Tokens Pixel Hunter, and Legend Tokens Game Over skins displays the options for a burst and full auto mode, which the Mastiff is unable to switch to in game.
