J. Edwards

Edwards is a UAC scientist and one of the few personnel who survived the initial invasion of Hell. He understandibly wanted to leave the Mars base and expresses his desire to do so when encountered halfway through the game. He lead the Marine though a dark tunnel that is filled with Imps and Maggots, lighting the area with a lantern while the Marine fights the demons off. Just before they manage to reach the exit, the pair are attacked by a large number of Imps; when the smoke clears, Edwards is revealed to have disappeared, leaving behind nothing but his lantern on the ground.
