The Jackhammer is a prototype automatic shotgun with a quick reload time, that fires multiple pellets with every shot creating a large fire-area, about the size to kill two men with a carefully aimed shot. It holds 12 shells per cylinder in both games, unlike its real life counterpart, which holds 10.
The Jackhammer is never given to you at the start of a mission. Instead, it is found in the hand of enemies that are in indoors. This weapon is the ultimate shotgun; its automatic fire makes can clear out crowds in seconds. Lone enemies stand no chance against it. It should be used in every close-quarters situation as soon as you get it. However, like the SPAS-12, it has poor range, so don't think about using it for any battles that aren't short range.

- When trading between the Jackhammer and another weapon in IGI 2, it is referred to as "Jack Hammer".
