Official

 * 1) In the yellow key building, get to the southwest room and use the skull switch there, then head to the southeast door and into the corridor to the north. Use the lift to go up, then out to the left. On the high ledge you come to, there will be a skull right by the lift exit. Use it, then quickly drop down and use the skull switch again. There will be a symbol on the south wall that you will need to quickly shoot. Do so, then take the lift back up to the high ledge. There will now be a closet with two shotgun guys (one on Hey, Not Too Rough or lower). Enter this closet and press on the southeast corner to find another switch. Use it to lower the wall north of the closet. Go there, then east and south, dropping to a small area where you can get a soul sphere to the east. (sector 135)
 * 2) In the large room at the southeast end, unlock the southwest lift and take it up, then head south and east towards a switch. Use the blue wall west of the switch, then head west and press the wall there to lower it. Ride it up and take the teleporter, then jump east and south to a platform with an invulnerability (not on Ultra-Violence or higher), medikits, and a chaingun. (sector 571)

Non-official

 * There is a red-floored staircase in the southwest of the non-secret part of the level, which is partially separated by a thin wall from the raised platform to which the staircase leads. The part of the platform between the wall and the staircase forms a thin ledge with a health bonus on it. To grab it, one needs to cross a linedef which temporarily opens a closet (sector 321) on the platform, containing a computer area map and a lost soul. The linedef is single-activation only.
