Doom 3: The Lost Mission

More than six hours has passed after the invasion has started. The last surviving Marine team, Bravo Team, makes their way through the Enpro Facility before a horde of demons ambushed them. One survivor barely escapes from his team's carnage. The Bravo team survivor is contacted by Dr. Richard Meyers, a scientist working on teleportation experiments in Exis Labs, and asked to help Meyers destroy an experimental teleportation array that was captured by the demons and is currently held deep inside Hell. The array is potentially powerful enough to send an army of demons all the way to Earth, hence Meyer's desperation to destroy it. To achieve this goal, the marine must acquire the components necessary to activate the Exis Labs teleportation system, then travel to Hell in order to destroy the teleportation array.
