The Heavy, or Heavy Weapons Guy, is a towering hulk of a man that hails from the USSR. The Heavy is the largest and possibly most dangerous class in Team Fortress 2. Boasting the most default health and devastating firepower from his trusty Minigun, the Heavy is no pushover. The Heavy's Minigun can inflict heavy damage at a high rate of fire, allowing him to mow down most enemies in seconds. The Heavy's movement speed is his main weakness. Revving up or firing his Minigun brings his already unimpressive speed down to a snail's pace, making him a very easy target for Snipers and Spies. His slow speed makes him more dependent on support from Medics and Engineers to keep him in the fight. Aside from decimating entire teams, the Heavy is able to provide further support for his comrades with an oft-required health boost via his Sandvich, which, when consumed, is capable of healing him to full health. It can also be dropped to provide an instant 50% health boost to the Heavy himself or his greedy teammates. However, if he isn't careful, an enemy may pick up the dropped Sandvich for a health boost of their own.
The Heavy is the face of Team Fortress 2. He appears prominently on box-art and promotional materials, starred in the very first Meet the Team video, and has appeared in all further videos to date.
