Walkthrough

 * Letters in italics refer to marked spots on the map. Sector numbers in boldface are secrets which count toward the end-of-level tally.

Secrets

 * 1) In the southern pipe room in the central building, one set of pipes in the east is arranged differently from the rest.  Press on this portion of the wall to find a compartment containing a blur artifact. (sector 248)
 * 2) In the Cyberdemon's cave, there is a stone passageway leading into a large stone room. (sector 195) Flip the skull switch in the southeast to unveil a compartment with a box of ammo, an armor bonus (only on Ultra-Violence or higher,) and a teleporter.  The teleporter leads to another compartment; open the wall directly in front of you to access a normally caged-off area at the entrance of the cave containing a megasphere and an invulnerability.  Go back into the teleporter you came from to be taken back outside of the cave.
 * 3) In the building accessible beyond the red key door, there is a giant section of wall in the southern hallway covered with electronics.  Open this wall to reveal a secret room with a backpack and a box of rockets. (sector 181)

Bugs

 * A shotgun guy (thing 130) is placed inside the zero-length sector of the cliffs located in northern part of the map, so it will be impossible to get 100% kills.
