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 also has limited ammunition.

Trivia

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