The full details of Valve's next Team Fortress 2 update have leaked in advance of their official release, revealing the achievements, unlockables and changes to the Pyro along with the two included community maps, all of which are due this Thursday, June 19.

Along with the previously revealed Axtinguisher, Pyro players will be awarded with the Flare Gun and Backburner for obtaining the 35 new achievements. As with the Medic update, weapons will be unlocked as Achievements are earned, with the Flare Gun coming first, the Backburner second, and the Axtinguisher last.

In addition, the Pyro's stock flamethrower will be updated with a new function, allowing players to blast enemies away with compressed air through a press of the alt-fire button.

Detailing the two community-created maps included with the update, Valve revealed CP_Fastlane as one of the two included maps. CP_Fastlane was created Arttu Maki--somewhat better known around these parts under as Shacker -sk-.

The other new map, CTF_Turbine, was created by Bill Johnston. "Awesomeball didn't make the cut," Valve marketing VP Doug Lombardi told Shacknews. "Sorry."

In celebration of these changes, Valve will be hosting a free Team Fortress 2 weekend Running from the morning of Friday, June 20 morning through the evening of Sunday, June 22, the promotion allows all registered Steam users to download and play the class-based mutliplayer shooter for free.

In related news, don't forget to watch Meet the Sniper, the latest in Valve's humorous and entertaining character portraits. The vignette even includes an in-game glimpse of the Flare Gun.

The complete achievement list and weapon descriptions are as follows:

Unlockable Weapons and Weapon Updates

Flamethrower Update
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.

The Flare Gun

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.

The Backburner

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 in survivability, it grants the Pyro an extra fifty health.

The Axtinguisher

The third Pyro unlockable is The Axtinguisher. This mighty axe guarantees critical hits on any enemy that's currently on fire, although it's significantly weaker against enemies who aren't. A great combination with the The Flare Gun, or with another Pyro buddy riding alongside doing the igniting.
