Editor's Note:

Although the original game for the PC was developed by Valve, this port to PS2 and Dreamcast has been done by GearBox and Captivation Digital Laboratories.

Added on: December 18, 2000



Deep under the ground of a remote US desert scientists are experimenting on creatures of unknown origin. You are Gordon Freeman, one of those scientists, and during a routine day at work something goes very wrong. A time rift develops, allowing aliens to slip into your reality. When you regain consciousness the facility is in ruins, aliens are everywhere and to make things worse, the government is sending the Marines in to clean up whats left - including any survivors.


The game is a FPS, so, you have to shoot every enemy that you're meeting. But you have also to duck or to take cover. Players will lead Gordon through Black Mesa and also drive a little train. Gordon will also have the opportunity to ask to guards or scientists to follow him or to stay where they are, it can be vital for advancing in the game.
