Take the shotgun to your left, which will lower the floor and reveal some shotgun guys (plus an arachnotron on Hurt Me Plenty (HMP) skill levels) waiting outside, then head east up two sets of steps to reach a ledge with two arachnotrons, zombiemen and chaingunners. There are two doorways at the south end, one of which is blocked by yellow bars - go through the open doorway to a ledge with imps/chaingunners, then head up another flight of steps to find the red skull key, which is protected by one or two mancubi along with demons and (depending on skill level) a Hell knight, revenant, cacodemon or pain elemental hiding behind a wall. You can run over the low wall holding the key to get back to the starting point, but watch out for various enemies teleporting in as you do so.

Go through either of the north doorways to enter a room with zombies who are guarding three locked doors. Only the north door will open for now, so pass through it and slay some more imps then drop into the water and go up the east steps to see a diamond button between two windows; the button will lower the windows, but will also open a monster closet behind you with imps, a chaingunner, a knight or an arch-vile, as well as a chamber in the water holding imps and shotgun guys. Go into that chamber to find a second button which will raise a bridge from the water, go back up the steps and cross the bridge you just raised before turning left to see the blue skull key, guarded by a mancubus and cacodemons.

Open the door in the south-east corner to return to the locked door room, but use caution as demons, imps, chaingunners and other enemies will teleport in around you. Go through the east door and follow the hallway to a ledge with a revenant, then drop into the water below and look in the south-east corner for a diamond button - this will open the wall in front of you to reveal with demons, as well as two closets containing cacodemons, imps and zombies behind you. Climb the stairs in the north-west closet to a circular room and press the button on the north-east wall to raise a bridge over the water, then cross the bridge and climb the steps ahead to reach the yellow skull key. Drop to the floor below and kill the arch-vile, mancubi and knights that teleport in, then open the yellow bars at the south end and drop down into a dark room with two barons of Hell. Press both buttons in the barons' alcoves to open the south door (which hides an arch-vile on HMP or higher), kill the enemies that teleport in then pass through the doors to reach the exit teleporter.

Other points of interest[edit]

A rocket launcher can be found in the water surrounding the starting point. Picking it up will cause enemies to teleport in at close range, so step away before firing.


  1. On the path leading to the yellow key, there is a straight bridge that needs to be raised by pressing a switch. Stepping outside of the building containing that switch and towards the bridge will lower an elevator on a section of a wall to the west in the water level, near the base of the stairs of the building with the switch. Ride this elevator up to find a path leading to a supercharge. (sector 121)
