Shotgun

The pump-action shotgun is one of the most versatile and useful weapons in the Doom player's arsenal.
 * 1) For skill 1 / skill 2+
 * 2) When dropped by enemy
 * 3) Without / with backpack

The shotgun packs a deadly punch at close range, and the grouping of the pellets is tight enough to make the weapon useful for medium-range attacks. In a pinch, the shotgun can be used for sniping, though the spread of the pellets makes it hard to do much damage at long range.

Packs of weaker enemies are particularly vulnerable to shotgun fire, and it is often possible to kill two or more zombie troopers or sergeants with a single shot. Against tougher enemies, such as cacodemons, it is usually best to run up close and fire at short range, then dodge the enemy's attacks as you reload. This tactic works well when combined with circle strafing.

The shotgun's main disadvantages are the slow rate of reloading (which can leave you open to counter-attacks) and the lack of long-range capability.

The shotgun fires seven pellets. Shots from a zombie sergeant's shotgun have only three pellets.

A shotgun contains 8 shells when picked up. Shotguns looted from the corpses of zombie sergeants contain 4 shells.

The images for the shotgun in Doom are of those of a toy shotgun called the "TootsieToy Dakota", manufactured by the Strombecker Corporation of America. An image of the toy is found here
