Half-Life 2 takes the suspense, challenge and visceral charge of the original to new heights of realism and responsiveness. Half-Life 2 opens the door to a world where the player's presence affects everything around him, from the physical environments to the behaviour - the emotions, even - of both friends and enemies. Gamers again pick up the crowbar of research scientist Gordon Freeman, who finds himself on an alien-infested Earth being stripped to the bone, its resources depleted and its population dwindling. Freeman is thrust into the unenviable role of rescuing the world from the wrong he unleashed back at Black Mesa.
Also included in this Game of the Year package is Counter-Strike: Source, the world's number one action game; Half-Life 2 Deathmatch, where you can experience the most visceral multiplayer game around; and Half-Life: Source, a special edit of the original single-player adventure, recreated atop Source for enhanced play.
