The SMG is a weapon in Crackdown 2. It is a starter weapon, alongside the Shotgun. It is mainly used for close quarters. It has low damage and effective range but a moderate fire rate. It has an upgraded version called Ultra SMG.
Due to the SMG's rate of fire a relatively low damage output it becomes ineffective at higher levels but makes a perfect sidearm when combined with either the Shotgun, Assault rifle or the Sniper rifle. The weapon can kill a Freak Rambler, the weakest of the Feaks, in almost one entire magazine and two or even three magazines for stronger enemies.
It should be noted that the Shotgun, the Assault rifle and the SMG all have an upgraded version which have higher damage outputs and ammo capacity.
