Secrets

 * 1) On the broke bridge over the nukage, head northeast and find a button on the south wall. Use it and quickly run to the lift to the west. At the top, use the switch and jump back to the bridge. Head north and to the dead end. Face east and look for a gargoyle switch. Shoot above it to open this secret, which is southwest of you and contains a box of ammo, a box of shotgun shells, and a soul sphere. (sector 367)
 * 2) See Secret #1. (sector 546)
 * 3) Open the red skull door and head into the blood, close to the steps where the walkway is. Shoot the switch, head up the steps, and get the radiation suit to the south. (sector 648)
 * 4) Press the satyr switch northeast of the yellow keycard to open the wall behind the keycard, containing energy cells, boxes of shotgun shells, a box of ammo, and a soul sphere. (sector 945)
 * 5) At the northwest end, head northeast from the steps and open the wall to find a shortcut to the nukage channel. (sector 818)
 * 6) Head south from the northwest end after using the switch in the middle room. In the brown area with the blue skull door, climb the steps, then look southeast and shoot the Hellgrowth behind the cage. This opens a wall at the southwest part of the base, with a box of shotgun shells and a megasphere. (sector 711)
 * 7) In the same area, open the west door and enter the nukage. Head southeast and flip the switch, then head northwest and get the plasma gun, rocket launcher, megaarmor, medikit, boxes of rockets, and energy cell packs. (sector 709)
 * 8) At the northeast end of the blood area, head on the walkway and look for a gargoyle switch to the west while on the walkway. Shoot above that switch, then jump off the walkway to the east and head northeast to a BFG9000. (sector 779)
