Half-Life 2[]

Once again players assume the role of Gordon Freeman, a scientist destined to save the Earth from hordes of gruesome alien attackers. Half-Life 2 takes computer games to a new level of realism with incredible in-game graphics that recreate familiar-looking city streets, and blend them with strange and grotesque monsters, resulting in a believable and at times unsettling environment. Objects and characters feature accurate physics properties, behaving with the appropriate mass, density, and physical properties of their real-life counterparts. Extremely intelligent computer AI result in enemies that plan, adapt, and respond to the player's actions.

Half-Life 2: Episode One[]

Half-Life 2: Episode One is the first of a series of stand-alone episodes based on Half-Life 2, the popular and acclaimed shooter epic. This episode takes place right after the events in Half-Life 2, as Gordon and Alyx flee from City 17, fighting against creatures who were previous blocked from entering the city. The Citadel you assaulted in Half-Life 2 is tumbling into chaos, and this event will have catastrophic effects on the surrounding area, prompting your escape. Secondary characters Alyx and Dog will have a much more significant role in this follow-up.

Half-Life 2: Episode Two[]

Half-Life 2: Episode Two is the second of a series of stand-alone episodes based on Half-Life 2, the popular and acclaimed shooter epic. Armed with new weaponry and vehicles, Dr. Gordon Freeman must race through a countryside riddled with an increasingly fierce Combine threat.


A unique take on puzzle gameplay by the makers of Half-Life. Portal is a new type of single-player game that changes how players approach, manipulate, and surmise the possibilities in a given environment in a manner similar to how the Gravity Gun changed our approach to how an object may be leveraged in any given situation.

Team Fortress 2[]

If you're ready for the challenge of true team-based online action, you'll find it in Team Fortress 2. With Team Fortress 2, you'll go into battle as part of a cohesive squad of fellow warriors all bent on the same goal - whether it's capturing points, gaining territory, or stealing enemy intelligence. And you'll do it knowing your teammates are watching your back as carefully as you're watching theirs. Begin by assuming one of nine classes, each with unique strengths and weaknesses. If you're looking for a straight-up fight, you can choose the Soldier or Heavy Weapons Guy. Prefer the shadows? You'll make a cunning Spy or Sniper. Medics and Engineers support their teammates through bravery and ingenuity. Focus the raw force of your team's talents through communication and strategizing.
