The Orange Box is the collection of games Valve Corporation released when they released Team Fortress 2, Portal and Half-Life 2: Episode Two; the collection also included the original Half-Life 2, and Half-Life 2: Episode One. If people pre-purchased the game on Steam, they also received Peggle Extreme for free. If players already own any of the games in the package – for example, Half-Life 2 – they are given the option to give the game away to a friend.
