New Info from Steam
http://www.steampowered.com/pyro/?pw=presspreview
The first Pyro unlockable is The Flare Gun, which replaces the shotgun. It allows the Pyro to ignite an enemy at long range, but does require careful aim on their part. It?s particularly useful for causing havoc on Snipers and Engineers who want to keep their distance.
I was right about the flare gun.
The second Pyro unlockable is The Backburner. This flamethrower is built for the Pyro who likes to ambush their opponents. It removes the compression blast capability, instead guaranteeing critical hits whenever it?s used on an opponent from behind. To aid insurvivability, it grants the Pyro an extra fifty health.
This makes it alot better for use on those pesky heavies.
And also
In addition to the three unlockable Pyro weapons,
we've made a significant addition to the base Pyro flamethrower. By hitting the alt-fire key, the Pyro is able to produce a blast of compressed air that knocks enemies away, and redirects enemy projectiles. It?s a highly versatile tool, allowing Pyros to get away from nearby enemies after igniting them, to kill enemy soldiers with their own rockets, or to separate enemy Medics from their healing targets
. In particular, it allows a skilled Pyro to contain an enemy invulnerability push, and even to separate the Medic completely if the surrounding terrain supports it.
Wow...thats awesome
