Kill the shotgun guys hiding behind the open door in front of you then go down the steps to reach a shotgun guarded by imps and demons. Follow the passage left or right until you get to a pair of doors, then open the north door and continue on to a chaingun guarded by a cacodemon. Head north into an octagonal chamber with some shotgun guys and an armor (taking it will cause spectres to teleport around you), then go west into a rectangular hallway and north into a room with damaging blue lights across the floor. Step over the lights to reach a button in the north-west corner (watching out for a demon hiding behind the pillar, or a baron of Hell on Ultra-Violence and Nightmare skill levels) then head due south through two more hallways to find the blue keycard sitting in an alcove. Watch out for shotgun guys, demons and barons teleporting into the area as you collect the key.

Return to the octagonal chamber and head east into another rectangular hallway, then north into a second chamber where some shotgun guys and demons will be released. Flip the switch by the west wall (which will allow you to collect the yellow keycard later) then return to the hallway and go east to a square gray junction before proceeding south to a door guarded by two cacodemons. Go through the door and press the button in the south-east corner, which will open a closet behind you containing lost souls, imps and two cacodemons and/or a baron, then head due north to another door and open it to find some shotgun guys protecting the yellow keycard. Taking the key will cause more shotgun guys and barons to teleport in to the room, as well as releasing lost souls from nearby alcoves.

Head south into the previous room and open the south-west door that was locked with the yellow key - you will enter a large room with four large pillars, which holds various monsters including a cyberdemon. Press the button in the south-east corner then leave the room by the west door to return to the central corridor, before heading round to the west side and opening the blue key door to enter a second large room with barons and cacodemons (plus another cyberdemon on Hurt Me Plenty or higher). Press the button by the south wall then return to the octagonal chamber at the north side of the level, dodging any demons and barons that have teleported in; the door to the north has opened, letting you reach the exit button.

Other points of interest[edit]

There are two small rooms at the north-west and north-east corners of the level that require the blue and yellow keys to open respectively. The west room holds a plasma gun and energy cells, while the east room holds a rocket launcher along with four boxes of rockets and armor bonuses.


  1. Follow the level as normal until you reach a chaingun guarded by a cacodemon. Go south-east from here to a floor lamp, then open the slime-covered wall next to it to find a supercharge. (sector 91)
  2. Go to the hallway in front of the blue key and look at the east wall to see two red warning signs. Shoot the flashing north sign to open the west wall, leading to health bonuses, armor bonuses, a backpack, a rocket launcher and a box of rockets. (sector 203)
  3. In secret #2, open the west wall to find a switch that opens the south wall, revealing a box of rockets, a megaarmor, energy cells and the red key. (sector 205)
  4. After getting the red key in secret #3, head to the center and open either of the red key doors to find ammo, armor bonuses, health bonuses and a BFG9000. (sector 92) The items will be guarded by zombies and barons.
  5. From the octagonal chamber, head east then south into a room with a nukage pit. Open the south wall with a candle in front of it to find a plasma gun, energy cells, and health bonuses. (sector 300)
