The Xbox 360 and PC versions of Valve’s deal of the century, a.k.a. The Orange Box, are now 100% finished and will be released on October 10th.

We call The Orange Box ‘the deal of the century’ because it includes five games for the price of one: Half-Life 2, Half-Life 2: Episode One, Half-Life 2: Episode Two, Team Fortress 2 and Portal. If for some reason you haven’t played Half-Life 2 and Half-Life 2: Episode One yet, then this deal is only so much sweeter for you.

Half-Life 2: Episode Two — the second installment in Valve’s episodic trilogy advances the award-winning story, leading the player to new locations outside of City 17.

Portal — a pioneering type of single player action game that rewrites the rules for how players approach and manipulate their environment – much like how Half-Life 2’s Gravity Gun reinvented the way gamers interact with objects in the game.

Team Fortress 2 — an all-new version of the legendary title that spawned team based multiplayer action games. The game’s daring new art style features the most advanced graphics of any Source-based game released to date.
