Included:
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 he cares about are counting on him.

Half-Life 2: Episode 1-
Stepping into the hazard suit of Dr. Gordon Freeman, you face the immediate repercussions of your actions in City 17 and the Citadel. Rejoin Alyx Vance and her robot, Dog, to once again aid the human resistance in their desperate battle against the totalitarian alien menace of the Combine. Episode One exposes Alyx's combat skills and knowledge of City 17 as the player battles side-by-side with her in this 4-6 hour adventure of greater density and detail than non-episodic releases.

Portal-
The game is designed to change the way players approach, manipulate, and surmise the possibilities in a given environment; similar to how Half-Life 2’s Gravity Gun innovated new ways to leverage an object in any given situation. Players must solve physical puzzles and challenges by opening portals to maneuvering objects, and themselves, through space.

Half-Life 2: Episode 2
As Dr. Gordon Freeman, you were last seen exiting City 17 with Alyx Vance as the Citadel erupted amidst a storm of unknown proportions. In Episode Two, you must battle and race against Combine forces as you traverse the White Forest to deliver a crucial information packet stolen from the Citadel to an enclave of fellow resistance scientists.

Team Fortress 2-
Unlike other “class-based” games that offer a variety of combat classes only, Team Fortress 2 packs a wild variety of classes which provide a broad range of tactical abilities and personalities, and lend themselves to a variety of player skills. Play as the flame-throwing Pyro, the room clearing Heavy, or the Spy, a master of disguises. Other classes include: Scout, Sniper, Medic, Engineer, Demoman, or Soldier.
