Submachine Guns

Submachine Guns (or SMGs) are a class of weapon available to all the player classes in Mass Effect 2 except Soldiers. They are smaller and lighter versions of the Assault Rifle and sacrifice range for an increased firing rate.

M-9 Tempest
Manufacturer: Elanus Risk Control Services

Rounds per minute: 925

Rounds per Thermal Clip: 50

Lightweight and easily concealed, this submachine gun fires in long deadly bursts. Very effective against shields and biotic barriers. Inaccurate at long range. Weak against armor. The commonality of kinetic barriers has led to increased demand for rapid-fire weapons like the Tempest. Produced by Elanus Risk Control Services for the Eclipse mercenary band, the Tempest is an expensive but deadly addition to anyone’s personal arsenal. It is acquired from a dead quarian during Tali's recruitment mission.

M-4 Shuriken Machine Pistol
Rounds per Thermal Clip: 24

A small high fire-rate two handed weapon, with pistol like qualities, capable of remove biotic barriers and shields with ease. Weak against armour. Very inaccurate at a long range, but can be deadly at a close range. Acquired sometime between meeting the Illusive Man for the first time and landing on Freedom's Progress to investigate the vanishing of the humans there.

Unlike the Tempest, the Shuriken is not fully-automatic, firing in 3-round bursts. This quality, combined with more managable recoil, makes the Shuriken slightly better at long range shooting than the Tempest.
