J. Edwards

Edwards is a UAC scientist that wants to leave the base. He leads 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.
