Super shotgun (Doom 2016)

The super shotgun, a staple weapon of the Doom series since Doom II, returns in the 2016 reboot. Like its Doom II predecessor, the new super shotgun is used by the marine by firing both barrels at once, and is then skillfully reloaded one-handed with two shells being placed into the breach at the same time. Its reload time is surprisingly short, seemingly faster than either the Doom II or Resurrection of Evil versions of the weapon. The UAC does not approve of the use of this weapon, having removed it from their arsenal, but still apparently tolerates some use by insistent veterans.

The super shotgun's formally obsolete status is reflected in its upgrade system, as it is lacks modifications available for other single-player weapons from combat support drones. Instead, the super shotgun receives a set of upgrades which are always active after acquisition. Consequently, the single-player version of the weapon lacks an alternate firing mode. In multiplayer, the super shotgun has an alternate mode that activates a retrofitted variable choke system, enabling narrower spread to project force over a longer distance.

Single player

 * Faster Reload -- Reduces the reload time by roughly 40%
 * Uranium Coating -- Causes pellets to penetrate multiple enemies
 * Double Trouble -- Allows the player to fire twice before each reload
 * This is commonly described as "firing each barrel separately"; although the weapon still deals the same amount of damage per shot. Ammo efficiency, however, is increased.

Pre-release behaviors
During the presentation, the gun displayed information for a "stun shot" modification, which should have belonged to the plasma rifle. This was likely a bug in the game's HUD system which was repaired in the interim between that presentation and release.

A promotional plaque placed next to a 3D-printed model of the weapon also implied that the variable choke system would occur as an alternate firing mode in the single-player campaign, which proved to be untrue as of release.
