The Machine Gun is a SMG with a very high rate of fire. However, the accuracy and power of the gun are relatively low in comparison to the K-SMG or the Soviet Rifle. The Machine Gun can only fire in full automatic, but it can be dual-wielded.

It only appears in TimeSplitters: Future Perfect. It makes its first Story mode appearance in The Russian Connection. It bears a very obvious similarity to the Heckler & Koch MP5K.
