Doom 64 Absolution PC: Map.15 ALTAR OF PLAIN (Super secret in two chance)

Map: http://numerometria.com/Doom/d64tc_ss_15.PNG Guide (map): To reach the Super Secret shrine you must jump from the pillar to the ledge at area 9. Here a secret door can be opened. Beware of the fire ball trap within! Best tactic is to stand in the doorway until the door lowers, hits you on the head and reopens. Quickly step into the room and back out into the doorway. This door is quite thick so the doorway is plenty deep enough to shield you from the fireballs. You can then enter the room to see a portrait of one of the games developers. Clicking the picture will reveal a hidden message.
