Press the satyr switch on your right to be lowered into a room with nukage; parts of the east wall will also lower to reveal two cacodemons, and there are two revenants behind the south fences. Take the super shotgun and box of shotgun shells (and armor on I'm Too Young To Die and Hey Not Too Rough skill levels) between the two north doors then head through the north-west door and follow the corridor round to a button guarded by two chaingunners and a shotgun guy; the button will open another door in the starting area that you will use later. Head west through another door and kill the shotgun guys and chaingunners protecting the blue keycard above you then go to the north-west corner of the room to find a button that will lower a lift next to it. Ride the lift up and go round the corner to another door, open it and kill the Hell knight and other monsters that are revealed in front of you then open the east wall with the UAC logo on it to get the blue key.

Return to the starting room and head through the north-east door (which opened when you pressed the earlier button) to enter a hall with imps on pillars, then open the west door to find the yellow keycard being guarded by more chaingunners and shotgun guys. Take the yellow key, then go back to the previous hall where several alcoves have opened releasing imps, shotgun guys and one or two cacodemons. Go back to the starting room and open the south door, step on the lift behind it to go down to a cavern then turn left and follow the passage round to some shotgun guys and demons guarding a green building. Go through the small doorway in this building and follow the tunnel to a square room, but do not enter it immediately as you will activate a crushing ceiling. There are six alcoves around the walls with buttons that must be revealed in sequence - start with the north-west alcove and make your way clockwise around the room, killing the chaingunners and shotgun guys that are revealed as you go, until you open the north-east alcove which contains a white teleporter. Step on the teleporter to reach an elevated ledge and follow it round to the red keycard.

With all three keys, go back to where you found the blue key and head west to find three locked doors. Open all the doors, kill an arch-vile waiting behind the second door on Ultra-Violence and Nightmare skill levels then step into the silver cube to finish the level.

Other points of interest[edit]
