Valve announced today that the Pyro Update for Team Fortress 2 will be made available this Thursday and contains three unlockable new weapons for the Pyro plus 35 new achievements. In addition, two user-created maps are included to highlight the work being done in the community and distribute those works to all TF2 players. In addition, the "Meet the Sniper" trailer will be released tomorrow, along with a web site dedicated to the Pyro update. Finally, to give everyone a chance to try the new weapons and community maps, Valve will hold another Team Fortress 2 Free Weekend via Steam, scheduled to begin this Friday at 11 am PDT.
