Team Fortress 2
The game was released on October 10, 2007, both as a standalone product via Steam and at retail stores as part of The Orange Box compilation pack. Both the Steam version and the retail The Orange Box compilation packs were priced at each gaming platform's recommended retail price. The Orange Box also contains Half-Life 2, Half-Life 2: Episode One, Half-Life 2: Episode Two, and Portal. Valve offered The Orange Box at a ten percent discount for those who pre-purchased it on Steam before the October 10 release, as well as the opportunity to participate in the beta test.
