Heavy is a class in Team Fortress 2. Heavy's arsenal includes: A Minigun, a Shotgun, and his own bare Fists. The minigun needs to spin up before firing, obviously. My pressing Mouse 2, you can spin up before firing to be ready for approaching enemies. Heavy has the most health in the game at 300. However, Heavy is the slowest class in the game, and is pretty much this game's only tank. Heavy's playstyle consists of ambushing enemies and defending the objective.
