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 Flammekaster, 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 instead guarantees Critical hits whenever used on an opponent from behind. The game counts the Pyro as being behind someone when the direction the victim is facing and the direction of the flames are roughly the same, within a window of about 73 degrees. More precisely, the dot product (a formula to check if two things are facing the same direction. The outcome is a number between 1 and -1, with 1 meaning they face the same direction and -1 meaning they face each other) of combining the normalized 2D vectors from the victim's facing direction and the flame particle's initial travel direction must to be over 0.8[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 Flame Thrower.

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.

Notes

  • The attribute "No random Critical hits" is missing from the description.[2]
