Secrets

 * 1) Lower the pillar containing the blue key and you will also lower the wall ahead. Open the metal wall here for a corridor leading down. Before heading down the steps, open the wall in the corner to find a light amplification visor. (sector 66)
 * 2) In the big courtyard where the red key is, head to the southwest pillar with the green armor. The switch in front lowers the pillar, but the switch behind it does something else. Press this switch and ride the lift back up. Head back down the steps and the opening to your left will have expanded a bit. Go down this path to find a berserk pack, a box of ammo, demons, spectres, and a way back to the starting point. (sector 201)
 * 3) Head down the corridor south of Secret #4 and around the cage. On the wall to the west is a small slit revealing a tucked-away skull switch. Press it and quickly head to the top of the steps to find a section has lowered. Drop in to reach the cage. Inside is a rocket launcher, a soul sphere, rockets, and shotgun shells. (sector 317)
 * 4) In the small wooden room on the west side of the map, shoot at the skull in the north wall, then shoot at the eye switch behind it. The northwest compartment will open, which counts as a secret. Inside is a Hell knight (baron of Hell on Ultra-Violence or higher) and a box of rockets. (sector 381)
 * 5) Go north down the corridor of steps mentioned in Secret #1 until you can go right. When you do, you will be in a small room. Approaching the metal walls will reveal eye switches. The one to the north is open, shoot it to open the northeast wall, which has another switch. If you use the eye switch here, continue down the corridor to see that the snakeskin columns have lowered, revealing a computer area map, stimpacks, and some imps. (sector 555)

Bugs
A multiplayer-only chaingun (Thing 130) and two multiplayer-only megaspheres (296 and 323) have no flags set for any of the three difficulty classes, so they do not actually appear in the level.
