The Collector's Edition of Half-Life 2 ships on a single DVD and includes:

• Half-Life 2
• Counter-Strike: Source
• Half-Life 1: Source
• Half-Life 2 T-shirt
• Prima book sampler.

By taking the suspense, challenge and visceral charge of the original, and adding startling new realism and responsiveness, Half-Life 2 opens the door to a world where the player's presence affects everything around him, from the physical environment to the behaviors -- even the emotions -- of both friends and enemies. Half-Life 2 requires an Internet connection for activation before you can play the game. Features:

Characters - Advanced facial animation system delivers the most sophisticated in-game characters ever seen. With 40 distinct facial "muscles," human characters convey the full array of human emotion, and respond to the player with fluidity and intelligence.

Physics - From pebbles to water to 2-ton trucks respond as expected, as they obey the laws of mass, friction, gravity, and buoyancy.

Graphics - Source’s shader-based renderer, like the one used at Pixar to create movies such as Toy Story and Monster's, Inc., creates the most beautiful and realistic environments ever seen in a video game.

AI - Neither friends nor enemies charge blindly into the fray. They can assess threats, navigate tricky terrain, and fashion weapons from whatever is at hand. (less)
