The area behind an enemy that will register critical hits for the weapon is approximately a 90 degree angle centered behind where the opponent is facing. This is significantly less than the Spy's backstab range, which appears to be any angle in the 180 degrees behind where a player is looking. The Backburner, like the Flamethrower and Degreaser, has the compression blast ability but uses 50 ammo per blast rather than 20 for the other Pyro primary weapons.
