Descent features true 3-Dimensional worlds with light-sourced shading texture mapping 3D morphing directional sound effects and sizzling music. You begin deep below the surface of Lunar Base I where an unknown alien race has taken over the chasm of the Post-Terran Mining Corporation. Lunge straight down mine shafts twist around never-ending tunnels and fight your way past robotic menaces in an environment that's truly 36-degree 3D ... move up down sideways and twist around shooting everything everywhere. Hang on to your senses as you drop straight down mine shafts on a ride that leaves you spinning.
