Descent is a 3D first-person shooter developed by Parallax Software and released for the PC in 1995. You command a small spacecraft that travels through the mines of the solar system while destroying the many infected mining bots. To upgrade the graphics on the original game install DXX-Rebirth.

There are 27 levels and 3 secret levels, with increasing difficulty. You need to find the reactor core, blow it up and then get out of there before the entire mine collapses on you. As an optional objective you can rescue the stranded miners who have been captured by the robots.

Getting lost is easy in a 3D environment as you fly upside-down and sideways through corridors and large cavernous rooms. You have the option of using keyboard only, or a mix of keyboard, mouse and joystick. To acess the secret levels you’ll need to find the hidden exits on levels 10, 21 and 24.
