Heavy Machine Gun

The Heavy Machine Gun is a new mounted weapon in Left 4 Dead 2. It replaces the Minigun from Left 4 Dead. 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).

Tactics

 * Tapping the trigger rather than holding down will have a similar fire rate, and will increase the duration of the Heavy Machine Gun before it overheats. This is possible due to no windup time unlike the Minigun from Left 4 Dead.
 * The Heavy Machine Gun uses the crosshair of whatever weapon (melee, gun, or items) that was equipped when the gunner started to use the Heavy Machine Gun. This typically means using a melee weapon or an item 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. Another thing is that the crosshairs of guns will expand (the expansion is indefinite), regardless of weapon, even the Sniper Rifle.
 * Much like its predecessor, the Minigun, the Tank, when controlled by the AI, will aggro on the Survivor who is manning the Heavy Machine Gun. This can be used to the Survivors' advantage if other Survivors are in danger from the Tank at close range, and the Tank needs to be pulled away.
 * In The Port, the Heavy Machine Gun manned by Louis, is the most helpful when trying to achieve KITE LIKE A MAN.
