Outpost 320, located one mile beneath the earth, the researchers make a critical error and something has now gone terribly wrong. All communications are gone, all means of escape destroyed and an extremely dangerous horde of ancient creatures is on the loose after a doorway to an unspeakable evil has been unleashed.
Eight survivors, two former research patients, three mercenaries, two researchers and a medic barricade themselves inside a remote area of the facility with little food, almost no ammunition and little hope of rescue.
Their one possible escape route is through thirteen levels of terror that will lead them to the surface. And one of them is not who they seem to be, but the darkness itself which has taken human form.
