A really fun game made by Interplay.

Sometime in the future, the Post Terran Mining Company is facing a problem. In many of their mines across the galaxy (or solar system, I forgot), their mining robots have gone crazy. They're attacking the workers and producing additional, and more deadly, robots.

Enter Material Defender. He's just been hired by Samuel Dravis of the PTMC to clean up the mess. Equipped with the Pyro-GX, a one-man ship designed for zero-gravity work, he has to fly into the mines and destroy the reactor cores in each one to stop the robot production.

Insane zero-gravity action. Wicked multiplayer. That just about describes Descent.
