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. Beside, all 3 new titles (and two previous HL2 games in console versions) ships with the then-new Source 2007 engine branch (formerly called The Orange Box engine branch).

Formerly, Peggle Extreme, a third-party Orange Box-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.

Updates from this bundle

In 2009, PC versions of Half-Life 2 and Half-Life 2: Episode One (runs on Source 2006), as well as 3 new games from this pack (), now runs on Source 2009. That same year, Peggle Extreme have been made available completely standalone from this package.

As of June 2011, Team Fortress 2 is now available separately for free, only on PC. 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 or by manually add it to Steam Library on it's store page.

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. On the same year, the engine for all 5 game has been updated again to Source 2013.

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), and was delayed to December 2007 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).
