J. Edwards

Edwards is a UAC scientist and one of the few personnel who survived the initial invasion of Hell. He understandably 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; Edwards is killed in the attack.

Note

 * Even if you manage to kill the attacking Imps before they reach Edwards, his death will still be triggered.
