This game combines great storytelling with intense action and advanced technology to create a frighteningly realistic world where players need to think smart to survive.
Throughout the game, both friends and foes behave in sophisticated and unpredictable ways, a result of Half-Life's powerful and innovative artificial intelligence. The intensity of the game also reflects the strong storyline, created by award-winning horror novelist Marc Laidlaw. Of course there are also a variety of exciting multi-player scenarios, and an easy-to-use interface that will have you connected to the game of your choice.
