Games included in The Orange Box compilation: The original Half-Life 2 - The player again picks up the crowbar of research scientist Gordon Freeman, who finds himself on an alien-infested Earth being picked to the bone, its resources depleted, its populace dwindling. Freeman is thrust into the unenviable role of rescuing the world from the wrong he unleashed back at Black Mesa. And a lot of people - people he cares about - are counting on him. Half-Life 2: Episode One - The player reprises his role of Dr. Freeman, who must immediately face the repercussions of his actions in City 17 and the Citadel. Freeman reconnects with Alyx Vance and her robot, Dog, as they continue their support of the resistance's battle against the Combine forces. 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.
