The shotguns of DoomRL have an cone-shaped area of effect attack that makes them unique and powerful. Shotguns never miss any target in their affected area, and they always do at least one damage to each target. The size of the shotgun blast varies from weapon to weapon. It is governed by two parameters: range and spread. The range of a shotgun determines how far the blast extends from the attacker, and the spread determines the half-width of the blast when it reaches it's furthest point.
Shotgun damage also diminishes over distance. Each shotgun has a reduction rating that determines what percentage of damage is taken off per tile of distance. This penalty is applied linearly, and it is applied even at point-blank range. Rounding is to the nearest integer (0.5 rounds to even).
Doom RL uses four different shotgun types:
| Shotgun Area of Effect Types | ||||||||||
| Name | Range | Spread | Reduction | |||||||
| normal | 15 | 3 | 7% | |||||||
| focused | 15 | 2 | 5% | |||||||
| wide | 8 | 3 | 10% | |||||||
| plasma | 15 | 3 | 5% | |||||||

To calculate a shotgun's area of effect, first a target square is calculated by extrapolating from the vector pointing at the manually targeted square. The true target will be a tile that is at the shotgun's maximum range with an approximately parallel vector. Then, for each tile in a (2 × spread + 1) side-length square around the target, the game traces out the path of a missile until it hits a wall. (Shotgun blasts go through enemies.) The missile paths are truncated if the distance along one of the axes becomes greater than the shotgun's range. For each tile that was traced out in at least one of the missile paths, damage is applied.
