Behind the scenes
In real life, the Jackhammer was a prototype design that failed to reach full-fledged production due to its manufacturer's bankruptcy. Very few functional prototypes (according to some reports, as few as three) were ever made with only one prototype left in existence. The game stays true to the weapon's reputation of controllability, even with automatic fire.
