Team Fortress 2 (TF2), the title PC Gamer's editors have called the most fun game ever made, is now available for the Mac via Steam, a leading online platform for games with over 25 million accounts worldwide.

Like all the titles Valve have brought to the Mac platform, TF2 features Steam Play which allows gamers to make one purchase and play the game on both the PC and Mac. In addition, TF2 supports cross platform play — so Mac gamers can play against/with PC gamers.

Those who play TF2 on the Mac will receive a free set of "earbuds" for their player character. Purchase the game this weekend on either platform and save 50% off the regular price. Or, try it via the Team Fortress 2 Free Weekend happening now on Steam.

In addition to all the TF2-Mac goodness, a new single-player training mode has been rolled out for both PC and Mac.
