Take the shotgun then head straight forward until you reach a small building with stimpacks and shotgun shells - barriers will rise to the east and south to bar your progress, and two Hell knights will appear in the building (on Hurt Me Plenty (HMP) skill level or higher, they will be joined by shotgun guys that appear in a niche in the north wall). Kill these monsters along with the imps and zombiemen that appear behind the barriers, then head east once the barriers drop until you reach a staircase and climb it, noting the two chaingunners that are released behind you along with a knight (or baron of Hell on HMP or higher) that appears at the top. At the top of the stairs, look through the southern fence and shoot the switch in front of you, which will open some bars to your right, then head across the bridge to collect the blue keycard. Watch out for one to three chaingunners that are released behind the blue key as you approach it.

Go back to the starting point, where two more chaingunners have been released, and try to open the blue key door - it will jam, and a group of demons, imps, shotgun guys, zombiemen and knights will teleport to the north side of the map. Fight your way back to the staircase and climb it, then press the "LOCKED" panel that has appeared on the east wall to open the blue door. Head back to that door, watching out for the caged shotgun guys (and arch-vile on Ultra-Violence and Nightmare) that are released at the bottom of the staircase as well as the demons that teleport in, and step through it to enter the room at the center of the map. Climb up the crates on the east side to get a chaingun and super shotgun if you need them, then go to the north wall - this will open a compartment in the south-west corner containing the red keycard, but you will need to fight off some arachnotrons as well as a pack of other monsters that teleport in to get it.

Taking the red key lowers a platform to the north, which holds an arch-vile as well as a rocket launcher and many rockets. Kill it then pull the switch in the north-west corner to lower the wall ahead, letting you go back to the north-west building where another "LOCKED" panel has appeared along with another wave of monsters - pressing this panel opens the exit door in the south-east corner of the map, but also brings in multiple mancubi. Head through the exit door, which has another arch-vile waiting behind it, and turn left (the door will permanently close behind you) then press the panel at the end of the passage to bring in a baron, which you will have to fight off while you wait for the exit switch to open on the opposite wall.

Other points of interest[edit]


Both secrets must be found before you pass through the exit door, as it will close behind you forever.

  1. Go across the bridge leading to the blue key. As soon as you find yourself above the starting point, step off the north side of the bridge to drop down to the raised part of the wall. Carefully navigate along the wall, walking north and east, until you see a part of the wall lower - a plasma gun, an energy cell and four rockets will appear there. (sector 437) Note that the bridge will become inaccessible as soon as you try to open the blue door for the first time; however, it might still be possible to reach this secret by utilizing an arch-vile jump.
  2. In the room behind the blue door, you can see a metal block in the north-east corner with multiple health bonuses on top of it, as well as a single armor bonus. Make sure you have enough health, since the only way to get up there is to utilize an arch-vile jump. A single arch-vile will come out of a closet next to the block when you take the red key. Once you reach the top of the block, the secret will register and you will also automatically grab a hidden megasphere. (sector 204) If you miss the first opportunity to get this secret, then a second arch-vile will appear after you open the exit door. However, it will be somewhat harder this time because there is no immediate line of sight between that arch-vile and the block, and getting the arch-vile to the right spot will likely cause it to resurrect quite a few monsters along the way.


Depending on the player's position during the fight in the room behind the blue door, some of the arachnotrons may fail to teleport in, making 100% kills unattainable.
