New TF2 Pyro Weapon Unveiled in Sniper Vignette

Though the official details aren't slated to arrive until tomorrow, the latest Team Fortress 2 character vignette contains a brief glimpse of Pyro's second unlockable weapon.
The device, which appears to be a blunderbuss, joins the Axtinguisher as one of the three unlockable weapons for the fire-happy Pyro class.

As with the recent Medic update, the weapons will be available to players once they earn a set number of class-specific achievements.
