• 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

With part 3 of the Half-Life saga in the horizon, this collection brings you from the start so you're ready to take on the third episode of this exciting trilogy. Half Life earns its popularity and reputation at being the first First Person Shooter game to use aq lifelike, realtime plot that pits you in the action as well as behind the trigger. Created by Valve Software, each episode employs advanced technologies for better, more realistic play. In Half-Life, you assume the role of Dr. Gordon Freeman, a recently graduated theoretical physicist who must fight his way out of an underground research facility whose teleportation experimentations have gone awry. The second part of the trilogy of episodic expansions for Half-Life 2, Episode Two picks up where Episode One left off?with Gordon and Alyx traveling out of City 17 and into a vast new environment.
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 people he cares about are counting on him. Intense, real-time gameplay of Half-Life 2 is made possible only by Source, Valve's new proprietary engine technology

Half Life 2 is probably the most boring game I have ever played. Team Fortress 2 is kind of fun, but I don't really play it either. Portal is the only game in this collection worth buying (it's fantastic!), and you can get it for about half the price of the Orange Box.

I wouldn't have bought the Orange Box if I hadn't thought Half Life 2 was a game I wanted to play...

I ordered this game used from GameUniverse and they sent me a pirated copy in Russian without the code for the internet. Do not buy from this company!!

I mostly purchased this bundle for TF2 and Portal. I find those two games to be entertaining and well done. I find HL2, however, to be quite disturbing. I can handle aliens rushing me -- in the dark even -- but, there are just some disturbing scenes of blood and mangled bodies in creepy towns that proves too much for me.

Not much to say. Team Fortress 2 is a great multiplayer game. Portal and Half Life 2 + episodes are great single player games, portal more for mechanics and half life more for story.

Great set of games to play.
Most of them you can play with friends.
Which is good.
Unless you have no friends.
Then it is not good.
