Heavy Machine Gun

The Heavy Machine Gun is a new mounted weapon in Left 4 Dead 2. It replaces the Minigun from the original. The bullets that it fires are extremely powerful, doing as much as to blow Common Infected to literal tiny bits. It appears to be as accurate or even more so than the Minigun, with a slower rate of fire. It has unlimited ammunition like the minigun. Compared to the minigun it does not require a warm up, but has a very long cool down (around a minute).

Trivia

 * The Heavy Machine Gun appears to be modelled after the Browning M2HB .50cal heavy machine gun.
 * The Heavy Machine Gun was originally going to have limited ammo.
 * The Heavy Machine Gun uses the crosshair of whatever weapon (Melee or gun) that was equipped when the gunner used the gun. This typically means using a melee weapon just before jumping on the the Heavy Machine Gun makes aiming a lot easier, as the crosshair intersects itself, showing where the bullets will go almost indefinitely.
