Essentials[edit]

Open the west door in the starting room to find some zombies guarding a P-shaped computer block, then walk around to the west side of this block to find a lift and press the button here to go down to a corridor. Slay the approaching monsters, then go to the UAC door halfway along this corridor; it will not open, but if you enter the corridor opposite this door then you will come to a room with zombies guarding a tech block. Look behind the block to find a switch and flip it, which will open the door you saw earlier but will also open the block to reveal a cacodemon (plus lost souls on Hurt Me Plenty skill level or higher) as well as opening the walls of the hallway to reveal a crowd of monsters. Go back to the UAC door to enter a room with a nukage pool (there is an armor here if you need it), then climb up the steps around the pool before heading west past some zombies to reach the red keycard.

Go back to the corridor and press the button at the north end to lower a lift; ride it up, then walk north-east through a blue-floored chamber to enter the circular room at the center of the map. Leave the room by the east doorway to get to a fork, then take the left (north) doorway and follow the hallway to a pipe room. Make your way to the east side of this room, watching out for any enemies hiding behind the walls, then follow the passage here around two corners to a red key door (watch out for the demons that are released behind you). Open the door and clear any waiting zombies and imps, then head through the south doorway and turn right to see some steps leading up to a room with more zombies. Open the west door and get a heavy weapon ready before entering the next hallway, as halfway along it the floor will lower and take you down to a blood pool with several imps and two barons of Hell. Fight them off while you wait for a spine in the south wall to lower and reveal a cacodemon, then press the skull switch behind it to lower a lift in the north-west corner that leads up to the yellow keycard.

With the yellow key, run through the west window to land in a hall near the starting point, then go back there and head down either of the north staircases to return to the circular room. Continue north until you reach another pair of staircases that lead to two locked doors with a chaingun between them. Open the west door (requiring the yellow key), then look behind the blue block in the next room to find a small chamber containing a button that will lower the lift next to it. Ride the lift up to a dark room with fences and note the door on your left; it will not open, but if you weave between the fences you can get to the other side of the door and find a button that will open the surrounding walls and reveal imps and demons. Fight them off then weave between the fences to get to the north end of the room before proceeding east to an open door, head through the next room to a room with a tan floor then follow this north to the blue keycard.

Go back to the room with two locked doors and open the east door this time, then fight your way to some steps at the north end and go down them to a second room with a switch. Flip the switch, then go back to the area with the two locked doors; a smaller door in the center has opened, revealing a button that you can press to raise a bridge from the nukage behind you (watch out for an imp waiting to ambush you). Cross the bridge and head down some steps to the exit door, then open it to find two zombiemen protecting the exit button.

Other points of interest[edit]

After opening the red key door, look left to see a candelabra next to a gray block. Head round this block to find a rocket launcher.

Secrets[edit]

  1. Take the hall east of the starting area and open the door. In the next room, drop down into the slime and run south and around clockwise to the lift. Press the part of the west wall with some green slime at the bottom to find a backpack along with six health and armor bonuses each. (sector 372)
  2. Come back into the slime mentioned in secret #1, but this time, run north and northwest through the dark passage to reach a plasma gun, an energy cell, a stimpack, and a teleporter back. (sector 528)
  3. After teleporting from secret #2, go west to the area with an arrow at the ceiling and look at the north side of the northwest beam; you will find a switch hidden behind a tall tech pillar. Press the button to raise a bridge from the slime pool mentioned in the previous secrets that will let you reach the door to the east, and a hidden area behind it (near the red door) that functions as a shortcut to the yellow key. (sector 203)
  4. In the blue-floored area west of the starting one, press the switch to lower the lift near the southern part of the area. Once you ride up, go to the east part of this hall and press the brown tech wall to the south to find a chainsaw. (sector 110)
  5. After pressing the switch in the southwestern part of the map, the hall to the north will open up, revealing a large slime area. Run to the northwest column of the slime area to find a berserk pack from its northwest side. (sector 119)
  6. From secret #5, go to the southwest part of the area and press the south brown wall (and another wall after that) to reach a stimpack and a box of bullets. (sector 169)
  7. From the circular room in the center of the map, go south and look at the west wall. Press the green panel to open the doors in the central room, where you will find a partial invisibility, two stimpacks, ten armor bonuses, two ammo clips, four shotgun shells, and two rockets. (sector 55)
  8. Exit secret #7, and as soon as you step on the blue-floored area, go north into the passage. At the end of it is a hidden switch to the north. Press it and go to the western part of the blue-floored area to an open hallway. (sector 143) You can find a rocket launcher, a box of rockets, a radiation shielding suit, four shotgun shells, an ammo clip, six health bonuses, eleven armor bonuses, and a switch that functions as a shortcut to the slime area mentioned in secrets #5 and #6.
  9. Come back to the circular room, head east, and take the north path at the fork. Follow this hall until you reach the new area. Press the part of its north wall that is lit (and has a bullet hole on it) to find two rockets and a teleporter that will take you to a room near the starting area with two stimpacks and a megaarmor. (sector 204)
  10. Open the blue door and go to the room with four alcoves near the switch. Enter the second one from the south and press the east wall to find a soulsphere. (sector 431)
