Duncan A. Mathews (Identification Number: 6917-38) 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 did not 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 Mathews, 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.
