Essentials[edit]

Go forward to a cage containing a cyberdemon (there is an invulnerability behind the cage if you need it), dispose of all the waiting imps and zombies then go up the stairs in the south-west corner to reach a lava pit. Run through the lava to collect the rocket launcher at the south end, then head through the western doorway - which will activate a pair of crushers above it - and go north to a T-junction. Continue north into a room with one or two barons of Hell and press the gargoyle switch here, then go back to the T-junction and go west through a now-open door to enter the room with the blue skull key. After taking the key, make sure to also collect the plasma gun opposite it.

Retrace your steps to the starting point and open the door here, then fight through the monsters to the south-west end and open the skin door between the blue skulls to find the red skull key; taking it will release more monsters into the room. Go back to the cyberdemon's cage and head through the doorway in the south-east corner, then open the blue door ahead and fight through a baron and other monsters to reach a staircase. Climb the stairs and go north to a set of red bars, open them then go due west to a radiation shielding suit; this entire area has a lava floor, and you need to watch for monsters ambushing you in the dark. Go to the north-west end and go down the steps here to find a spectre (or cacodemon on Hurt Me Plenty skill level or higher) guarding the exit hole.

Other points of interest[edit]

From the rocket launcher room, go east to enter a fleshy room with a megaarmor.

Secrets[edit]

  1. Enter the room west of the start and use the north-east corner wall. Ride up and press the switch, which raises a pillar to the south. Cross south-west to get a stimpack. (sector 25)
  2. South of the blue door leading to the east end, you will find a stimpack and an energy cell pack. (sector 109)
  3. On the opposite side of the steps where secret #2 is, use the switch to reveal a lift behind you. Ride up and head south to get a backpack. (sector 257)
  4. In the lava area at the east end, find a corridor going east to a medikit, a radiation suit and shotgun shells. (sector 227)
  5. Use the lift east of secret #4 to find a supercharge and a megaarmor. (sector 224)
  6. Go behind the exit hole and lower the east wall to get the BFG9000. (sector 256)
