Box of shotgun shells

A box of shotgun shells is an open slide-cover shotshell box containing 20 shells for both the shotgun and the super shotgun (40 at the I'm Too Young To Die and Nightmare! skill levels). It is light gray in Doom and Doom II, and dark brown in Doom 64.

For considerations, the two shotguns use shells to unequal effect, and the shotgun operates differently for the player and the shotgun guy. When wielded by the monster, the shotgun produces only three pellets when fired, while in the hands of the player the weapon fires seven pellets per shell. Furthermore, the super shotgun fires a hefty twenty pellets, potentially causing nearly three times the damage the shotgun inflicts, while using only twice the ammunition.

Each pellet does between 5 and 15 hit points of damage (determined using Doom's pseudorandom number generator); the same as a bullet fired by the pistol or chaingun.
