M-4 Shuriken Machine Pistol
 In-Game Description
A common but effective submachine gun. Fire three-round bursts, and can be pulsed for a higher rate of fire at the expense of accuracy. Very effective against shields and biotic barriers. As kinetic barriers have grown in popularity, so has the popularity of submachine guns. Manufactured by the Elkoss Combine, the Shuriken machine pistol has a reputation for being deadly and easy to use, but is weak against armor.
The M-4 Shuriken Machine Pistol is acquired during the mission to Freedom's Progress. It is the default Sub-machine Gun that the player has access to. Every class with the exception of the Soldier can use the Shuriken.
