June 23, 2011—Valve, creators of bestselling game franchises (such as Half-Life, Portal, Left 4 Dead, and Counter-Strike) and leading technologies (such as Steam and Source), announced today that after four years and over 200 updates, its popular and critically-acclaimed online action game Team Fortress 2 (TF2) is now Free To Play (F2P).

New players interested in experiencing what PC Gamer calls "the most fun you can have online" will have access to training and offline practice modes, so they can hone their skills before jumping into the ever-expanding TF2 universe.
To celebrate the launch of the Über Update, Valve has released "Meet the Medic," the latest in its series of TF2 animated shorts.
