Secrets

 * 1) Head to the entrance of the building on the west side, then open the west wall at the shotgun. Head past the box of shotgun shells to get to a chaingun. (sector 32)
 * 2) In the entrance of the building, climb the steps and use the left eye switch. Go west and cross the bridge, then get on the platform to the right and go through the wall to get to a backpack and a switch. The switch will lower the southwest platform where the bridge is, leading to some ammo, as well as the cacodemon closet south of the platform, with more ammo and medikits. (sector 112)
 * 3) In the throne room, head to the east column and take the lift up. At the top, open the east wall and jump east to two passages, leading to different supplies. (sector 126)
 * 4) In the throne room, open the red door to the left of the throne, then find a wall at the northeast end with a candle in front of it. The teleporter here takes you to a soul sphere. There is also a backpack northwest of the teleporter, and some ammo and a medikit on a platform below. (sector 185)
 * 5) In the blue key area, enter the northeast corridor, then use the switch to the left. Go back and use the switch to the northwest to find a radiation suit. (sector 269)
 * 6) In the throne room, open the blue door to the right of the throne and go north into the corridor. Open the west wall where the candle is and take a lift to rockets and medikits. (sector 190)
 * 7) Open the yellow door and open the wall that is just north of the entrance, behind the northwest column. Take the lift to get a stimpack and rockets, and take the teleporter for health bonuses. (sector 259)
 * 8) Open the yellow door and head around the central structure to the east side. Open it from there to get a box of ammo, a box of shotgun shells, and a megaarmor. (sector 215)
