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 modeled 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.
 * The heavy machine gun replaces the minigun due to the minigun's lack of use in campaign and that the minigun was not very beneficial.
 * Ironically, neither of the heavy machine guns in the game are very useful. In The Plantation, the gun overlooks the hedges, but very few, if any, of the Common Infected come that way, and the few that do are either protected by the hedges, or come from the sides where the heavy machine gun cannot aim. In The Bridge, the gun appears after you have crossed the bridge, and the end-of-finale phase has begun. The Tank will spawn behind where the gun is placed, and combined with the fact that you're almost at the rescue point anyway, the only use for the gun is to cover players still coming off the bridge - except that they are largely hidden behind concrete barriers and other vehicles. And let us not forget the extremely long cooldown period, which renders this weapon worthless if a player who does not know how to use it gets it before anyone else. The only other instance in which it may prove useful is during a Survival game.
 * The Machine Gun is mistakenly listed as "Minigun" in the stats.
 * The Machine Gun was probably set up by the the Army in quarantine areas or at checkpoints to protect the Survivors, where the Infected may have gathered.
 * Like the Minigun, the Heavy Machine gun can cr0wn a Witch. Unlike the Minigun, however, there is never a chance to do so; no Witches spawn after the scaffolding area that you use to enter the The Plantation, and Witches can't spawn on The Bridge.

Known Locations

 * The Plantation - Located at the center of the top floor overlooking the garden at the rear of the plantation house.
 * The Bridge (Left 4 Dead 2) - Just before the drop-off to the helipad, the heavy machine gun is located on a truck directly opposite the drop down.
