While it is mainly seen mowing down infantry, the machine gun's incredible versatility has seen it put on 'Mechs. The heavy machine gun's "no-heat continous-fire" ability makes it a useful asset in any MechWarrior's arsenal. Heavy machine guns are particularly useful in quad mountings like in the Cicada or the Spider. Their rapid fire makes them prime candidates for making "critical hits".


Currently, the Heavy Machine Gun does very little damage, although it does more than the Machine Gun and the Light Machine Gun, at the expense of shorter range. However, it does incredible damage to internal structural components. It has a 39% chance to deal 1 Critical Hit, 22% chance to deal 2 critical hits, and 6% chance to deal 3 critical hits. If used correctly the machine guns can be used to devastate even assault mechs.
