The Submachine Gun is an automatic weapon with two fire modes: Semi-auto & Full-auto. By default, it is set on Semi-auto. Compared to the game's other automatic weapon, the Machine Gun, the Submachine Gun deals more damage (a little over 50% more damage per shot), but ammo for it is more difficult to find around town. However, it loses accuracy at long range.
- Both versions of the Submachine Gun are based on the Heckler & Koch MP5, the ED/P2/PL version being based on the standard version, and the Redux version based on the shortened version, the MP5K.
