Secrets

 * 1) As you approach the blue key, the walls to the right will open up. Look at the fenced-in lights and notice one of them is blue instead of yellow. Shoot at this light to reveal a hidden switch near the key, which will lower the megaarmor in the orange-floored chamber ahead of you. (sector 615)
 * 2) Once the starting lift lowers, head directly west and follow the hall and the upper ledge going northwest. When you reach a hall with terminals and gray stones, go east until you spot an orange emblem in the wall. Press on it and drop down to the west, where you will find energy cells. If you head further on the ledge, a switch will appear, which will open up walls across the nukage as well as reveal Secret #7. (sector 769)
 * 3) Drop into the nukage at the southeastern portion of the map, then follow the trail of health bonuses to a teleporter. Take it and press the switch, which will open the doors to the east. When you can, head back to that area and enter the hall. Head towards the super shotgun at the south end and look east. Press the panel, then leave the hall and get back outside. Turn south and jump into the nukage outside of the fence. Go west to find medikits, energy cell packs, and a backpack. (sector 1237)
 * 4) Drop into the nukage at the southeastern portion of the map, then follow the trail of health bonuses to a teleporter. Take it and press the switch, which will open the doors to the east. When you can, head back to that area and enter the hall. Look to the north and shoot at the column; there is a switch behind this column that reveals a switch at the base of the steps below. Flip that switch to trigger a lift. Ride it up and head west to the next switch, which will lower the blocks to the south. In the big area at the south end, use the teleporter to appear at the northern portion of the map, lowering the wall ahead of you and entering the plasma gun room. Leave this room by entering the hall to the east, but immediately turn back around and head back west, towards where you teleported, then head north and through the corridor before a block rises. You will find a soul sphere. (sector 1800)
 * 5) At the northeasternmost portion of the map drop into the nukage and head for the southernmost end. This will cause the slimefalls to lower revealing a plasma gun and energy cells. There are three sectors here, all of which count for the same secret. (sector 1373)
 * 6) Head a bit east and then north from the starting lift and go into the nukage. Get on the platform with two medikits and press on the gray wall next to the red panel to lower that panel. Take the teleporter to find a green armor, a box of shotgun shells, energy cells, and a computer area map. (sector 1649)
 * 7) If you had used the switch at the end of Secret #2, you will be able to reach two boxes of rockets inside Secret #6. (sector 1655)
 * 8) From Secret #7, if you were to drop into the nukage, you will teleport to the ledge at the south end of the map where you can see the BFG9000 in the middle. This same BFG9000 was visible from the opposite switch, which was mentioned in Secret #3 as the switch that opens the doors to the east. The switch on your side will lower the opposite switch, and by then you can re-enter the teleporter mentioned in Secret #3 to get the BFG9000. (sector 1321)
