Hud icon of the Assault SMG.
The Assault SMG is a new SMG in the GTA IV DLC The Ballad of Gay Tony. It is based on the Belgian FN P90, and it is classified as a personal defense weapon (PDW) as it features a cartridge size somewhere between a pistol round and an assault rifle round (the P90 uses the proprietary 5.7x28mm cartridge). It is outfitted with a functional suppressor as minimal muzzle flash is produced when the weapon is fired, however it cannot be used for stealth attacks. The Assault SMG is one of the first bullpup weapons offered in the GTA series. It is perfect in gunfights and easy to carry due to its light and compact size. It is more accurate than the SMG and holds 50 rounds per magazine, however it has less stopping power, a common criticism of personal defense weapons. Unlike other SMGs, the Assault SMG cannot be used by the driver of a vehicle. NOOSE's Tactical Response Unit and the FIB use this weapon against the player in addition to their regular SMGs and Carbine Rifles.
- A bullpup configuration has the action and magazine of the weapon located behind the trigger to reduce the overall length and weight of the weapon.
- Originally, the SMG is not meant for the player to use in drive-by, but a glitch may make this possible. First of all, the player have to dial in the cheat codes for the "Advanced Weapon" Set, and also the "Poor Weapon" Set. Now, get a car or a motorcycle, and be sure that you have the poor weapon set. Change the weapon to the Micro-Uzi by pressing X and then dial in the code for the Advanced weapon Set. Now, you'll be able to fire the P90 in a drive-by postion.
