Combat shotgun

The combat shotgun.

This article is about the weapon in Doom (2016). For other versions of this weapon, see:

• Shotgun
• Shotgun (Doom 3)
• Combat shotgun (Doom Eternal)

The DS-117 combat shotgun is a weapon in the 2016 Doom game. Forged from a quality titanium-steel alloy, its qualities include high reliability, a fast rate of fire, and high-velocity, high-impact shot. Like most of the weapons in this incarnation of Doom, the combat shotgun can be modified and upgraded with attachments which impart special capabilities beyond the base weapon's attack characteristics. It is more limited in effective range than its classic counterpart, though not quite to the extent which the Doom 3 version suffered.

One notable cosmetic aspect of the shotgun is that the chamber is located at the upper portion the weapon instead of below of the weapon, which is revealed in a hidden reload animation which can be seen using glitches.

Modifications

Explosive Shot

An alternate ammunition for the combat shotgun based on octanitrocubane explosive and a glycerin fuse. Shot embedded in the explosive is dispersed upon impact, creating an effect similar to the frag grenade, damaging targets over a wide area. This extends the weapon's utility against multiple targets.

Charged Burst

An Argent-charged compression reloader fires off a volley of three shells in a quick succession. The compression reloader component used to drive this fast firing is powered by Argent energy, and requires a cool down period after use.

Pre-release

• A shotgun that appears in the cancelled Doom 4 1.0 reboot is similar to the final game's appearance. It appears to be slimmer than the final version and is coated in metallic black. The animation when it fires is similar to the original version of the shotgun, firing at the right side before turning the weapon over to the other side to pump it.
  • A shotgun with the same animation but with a grayish color can be seen in glory kill pitch animation assets from the original project, presented in 2013, during the "rolling reboot" process of development.

• 

  Shot from the 2012 concept teaser trailer, the player is about to shoot at some possessed soldiers.

• 

  The Slayer takes out a shotgun to shoot a demon similar to the prowler.

• The development names for the shotgun's mods were Triple Burst and Pop Rocket. Later, Triple Shot and Pop Rocket were reused as names for the Full Auto and Sticky Bombs mods in the concept stage of Doom Eternal's combat shotgun.
• In the available clips of gameplay from QuakeCon 2014, the shotgun does not have any modifications; perhaps they were not ready at the time of the demonstration.
• During the E3 2015 Foundry gameplay showcase, it could be observed that the animation of the charged burst mod being installed was the same as the animation for the explosive shot. When charging, the position of the weapon changed to the center of the crosshair, instead of zooming in on the shotgun.
• In the game's strings you can find mention of several unused weapon mods.

Trivia

• The wrap-around nature of the trigger suggests the weapon is fired electrically, as opposed to current-day weapons, which are fired mechanically.
• In The Art of DOOM Eternal there is concept art of soldiers carrying this weapon.
• In the game, you pick up the shotgun from a corpse of a deceased UAC marine. This suggests that the combat shotgun was a very popular weapon within the UAC.
• An animation with pumping the shotgun after a shot can still be seen in the game if the player turns on classic pose mode in the settings.
• The rocket launcher and Gauss cannon have unused reload animations that are exactly the same as for the shotgun. Most likely, these were placeholders during development, until the weapon reload was scrapped completely.
• In some unused glory kills, the Slayer uses the shotgun to shoot at the enemy's head or body, or would use its buttstock to hit the enemies, and even use it to split imps in half. Most likely, they are leftovers from the unreleased Doom 4.
