Package: The Orange Box

The Orange Box is a bundle that includes five titles from Valve: Half-Life 2, Half-Life 2: Episode One, Half-Life 2: Episode Two, Team Fortress 2, the sequel to the game that put class-based, multiplayer team warfare on the map, and Portal, the game that blends puzzles, first person action, and adventure gaming to produce an experience like no other.

Formerly, Peggle Extreme, a third-party Valve-themed game by PopCap Games, was also included in this pack, until 2009, when it was made available for free and standalone from this pack.

As of June 2011, Team Fortress 2 is now available separately for free. Nonetheless, TF2 will not be added to a user's library unless the user has purchased the game prior to going F2P or has purchased The Orange Box.

And around 2013, during and after SteamPipe update, the PC version now includes Half-Life 2: Lost Coast, Half-Life 2: Deathmatch, and Half-Life Deathmatch: Source, despite not being mentioned on the bundle page.

A console version of this package (for Xbox 360 and PlayStation 3) is also available. Those versions are still running on Source 2007. The PlayStation 3 version of Orange Box is developed by  Electronic Arts (EA) due to Valve having difficulties developing for that platform at the time, like many other developers (until Portal 2 came out along with Sony improving documentation of the PS3 hardware).
