Combat shotgun (Doom Eternal)

The combat shotgun returns in Doom Eternal, with properties similar to its previous incarnation from Doom (2016). It is the Doom Slayer's personal weapon before hunting down the Hell Priests, as he keeps it inside of a case during the introductory cinematic.

The weapon retains an explosive shot mod, albeit now firing an explosive gel that adheres to targets before detonating, requiring a reload after three shots (with remaining ammunition indicated on the crosshair). The explosive shot also deals extra damage to weak spots, enabling one to destroy, for example, the arachnotron's cannon or the revenant's rocket launchers. Replacing the original charged burst is a new automatic firing mode wherein the weapon behaves like a, with three rotary barrels.

Modifications

 * Sticky Bombs
 * The combat shotgun can fire explosive projectiles that stick to surfaces and enemies, detonating shortly after they make contact with their target; if the sticky bomb attaches to a destructible weak spot (e.g. the Arachnotron's turret), it will produce a larger explosion that deals more damage. If fired into a cacodemon's open mouth, it will eat the bomb and become staggered for an easy glory kill. Three sticky bombs can be fired before the weapon needs to reload.


 * Full Auto
 * Briefly converts the combat shotgun into an automatic weapon, greatly increasing its fire rate and making it more effective against strong but slow-moving enemies. However, it will consume ammo at a faster rate. It is one of the few weapons able to damage stone imps.

Lore
Despite a wealth of armament options for the modern combat specialist, this trusty workhorse remains a firm favorite among operatives. When matched against super-heated plasmoids or gauss driven projectiles, the ballistic impact of the Combat Shotgun holds its own. The simplicity of the design ensures the weapon is extremely quick and reliable, yet the vast array of ammunition types make it versatile and flexible. Colloquially known as the "Crowd Appeaser", a locked and loaded Combat Shotgun will pacify even the most riotous of assailants.

Trivia

 * In a minor break of series tradition, wherein the protagonist usually starts off with a pistol, the Doom Slayer starts off with a combat shotgun, along with the Doomblade, in Doom Eternal.
 * The pistol was implemented in the game, but it is unobtainable outside of console commands.
