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 room with the blue key, shoot the skull switch in the northwest corner for a box of ammo, a box of shotgun shells, and stimpacks. (Sector 36)
 * 2) At the start, press the west skull switch for a shotgun. (Sector 51)
 * 3) At the start, open the northeastern door and proceed down the right passage until you find a gargoyle face to the left. Open it for a spectre, some stimpacks, a box of ammo, and a box of shotgun shells. (Sector 70)
 * 4) At the start, open the northeastern door and proceed down the left passageway. At the U-bend, the light fixture will open revealing some stairs with imps and a chaingun. This counts as nine secrets (Secret #4 and Secrets #6-13). However, Secret #13 cannot be accessed without the noclip cheat as the sector is not possible to register due to the chaingun platform. (Sector 72)
 * 5) At the start, open the northeastern door, and just to the left of the door, open the wall for a box of ammo. (Sector 80)
 * 6) (Sector 91)
 * 7) (Sector 92)
 * 8) (Sector 93)
 * 9) (Sector 94)
 * 10) (Sector 95)
 * 11) (Sector 96)
 * 12) (Sector 97)
 * 13) (Sector 98)
 * 14) Near the red key room you will see a cacodemon through a window. Approach the window and open the wall to your right for boxes of shotgun shells and a stimpack. (Sector 203)
 * 15) Secrets #15 and #16 are at the exit, a medikit and a box of shotgun shells hidden behind the exit signs. Although the items are obtainable, the secret sectors themselves are actually inaccessible unless the player uses the noclip cheat, because both sectors are 16 units tall and 32 units wide, too small for the player to enter. (Sector 242)
 * 16) (Sector 243)
 * 17) Through the northeastern door at the start, proceed all the way down the left passageway until you reach the switch at the end. Then backtrack and you will find your previous route was blocked off, but a new passageway nearby is open. Find a gargoyle face along this passageway and open it. You will find a room with damaging blood, demons, stimpacks, and a plasma gun at the very end of the room. (Sector 267)
 * 18) West of the outdoor area with lots of former humans is a long metal passageway ending with a teleporter leading to the yellow key. Before entering it, look to the right to find a clean metal wall. Open it to find a lava-filled room with ammo boxes, stimpacks, and boxes of shotgun shells. (Sector 315)
 * 19) After opening the blue door you will come to a red brick room with some teleporters and monsters. A wall on the northwest side of this room can be opened. Inside is some ammo, a backpack, some stimpacks, and spectres. (Sector 328)
