Submachine Guns

Submachine Guns (or SMGs) are a class of weapon available to all the player classes in Mass Effect 2 except Soldiers. The following squadmates also utilize submachine guns: Miranda, Mordin, Samara/Morinth, Thane, Kasumi, Liara, and Dr. Amanda Kenson. Submachine guns possess a bonus to damage against shields and biotic barriers, however, they are weak against armor. With their large thermal clip sizes and total ammo capacity, they fill the role of a backup suppressive weapon, while retaining moderate accuracy.
