This flamethrower is built for the Pyro who likes to ambush their opponents.
Backburner publicity blurb

The Backburner is an unlockable primary weapon for the Pyro. Its appearance is very similar to the default Lança-Chamas, with the exception of a team-colored part on the front of the weapon that resembles a dragon's head.

The Backburner does not roll for random critical hits, but it guarantees critical hits whenever it is used on an opponent from behind. The game counts the Pyro as being behind someone if the angle between the direction the victim is facing and the direction from which the flames are coming from is too large. More precisely, this is done using the dot product between the vector of the direction the victim is facing and the vector of the direction of the flames. If this dot product results in a number greater than 0.8, then the player is seen as being behind and deals crits; if the number is less than 0.8, then normal damage is dealt.[1]

The Backburner, like the Flame Thrower, Degreaser, Rainblower, and Dragon's Fury, has the compression blast ability, but uses 50 ammo per blast rather than 20 like the Pyro's stock flamethrower.

Afterburn reduces healing and shield resists from a Medi Gun by 20%.

The Backburner is automatically given to any player who obtains 16 Pyro achievements.

The kill icon for the Backburner was contributed by NeoDement .

Note: Flame damage is proportional to particle lifetime instead of distance from target. Unlike most weapons, Critical hits are also affected by the scaling. Additionally, there is a very slight damage variance (±0.08 / particle) due to differences in particle angles.
