Valve’s just released a new map, gametype, and a host of new weapons and achievements for the Medic class in Team Fortress 2, the first of a coming wave of achievements and additional weapons. To celebrate, they’ve announced that everyone can play Team Fortress 2 for free this weekend. All the details are here. TF2 is my current fave FPS. If you haven’t tried it, I encourage you to give it a shot this weekend since it will cost you nothing, and the full game is like $19.99 and more than worth 3x the price.
