Something has gone terribly wrong at research 320, a secret facility one mile
beneath the
earth's surface. All communications has gone, all means of escape destroyed.
Eight survivors
of the outpost barricade themselves inside an area with little food, almost no
means of defense and little hope of rescue. Their one possible escape route is
through thirteen levels of terror that will lead them to the surface. But one
among them is not who they seem to be, the darkness itself which has taken on
human form!
