The Backburner is one of the three new weapons added with the Pyro Update. The weapon becomes available after unlocking 15 Pyro Achievements, thus reaching the "Pyro Milestone 2".

The weapon works in the same way the Flamethrower: it uses fire to deal damage and set enemies on fire. As the name implies, it will cause critical damage whenever a player hits an enemy on his or her "back".
