Duncan Mathews

Duncan Matthews was a Systems Analyst assigned to Mars City. Like many of his fellow co-workers, he became increasingly disturbed by the strange incidents that were occurring in the city. He sent a request to Mars Security for Armor and a Plasma Gun, claiming that he didn't feel safe. Mars Security granted his request for armor, but did not give him a Plasma Gun since civilians were not permitted to have weapons. Unfortunately for Matthews, he was unable to make use of the armor, as the base was invaded by the forces of Hell later that day. He was killed (possibly by an Imp) in the ACO Lift Junction.

The player can find Matthew's body on a catwalk in the ACO Lift Junction when revisiting Mars City. His PDA will grant the player access to his office, where the armor requested in the email can be found.

In his request, Matthews notes that a lot of equipment is left carelessly around the base. This is a possible reference to the fact that during the course of the game, the player will often find free weapons and supplies on the ground.
