Heavy Machine Gun

The Heavy Machine Gun is a new mounted weapon in Left 4 Dead 2. It is unclear whether it replaces the Minigun outright or whether both weapons will appear in the game. It appears to be more accurate than the Minigun, albeit 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 much longer cool down.

Trivia

 * The Heavy Machine Gun appears to be modeled after the Browning M2 .50cal heavy machine gun.
