Backburner
“ | 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 Flame Thrower, 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 determines whether or not the player is behind an opponent by using the dot product between the vector describing the direction the target is facing and the vector describing the direction of the flames. If this dot product produces a number greater than 0.8, then the player is registered as being behind and deals crits; if the number is less than 0.8, then normal damage is dealt.[1] In simpler terms: if the angle between the direction the target's model is facing and the direction from which the flames are coming is too large, the game does not consider the player behind the enemy.
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.

Bugs

- The Backburner can be inspected while being fired.
Trivia
- The Festive variant resembles Rudolph the Red-Nosed Reindeer.
- At some point in development, there were no eyes painted on the Backburner, as shown on the Pyro Update page.
