It is a single-barrel shotgun designed for military use.It operates similar to the Sawed-Off Shotgun, but has a higher firing rate, but shorter range and less damage per shot, even though it has a tighter pellet spread. The firing rate gives it a high recoil, making it difficult to maintain accuracy.
When using the Extra Crispy modification the player has access to the combat shotgun during the original single-player campaign, assuming one has The Nightmare Levels installed.
