Essentials[edit]

Kill the shotgun guy and zombiemen in front of and above you, then use either of the silver lifts to get to the upper level before going to the south-west corner to get a chainsaw. Look through the windows to see chaingunners on a platform, then shoot the red switch next to the middle column on this platform to open two marble walls to the east and north, then step through either opening to see a Hell knight guarding a skull switch. Press the switch to lower the floor, step away from it to avoid an ambush by demons and revenants then press two more buttons in the north-west and south-east corners to lower the outer wall, revealing a shotgun and megasphere and bringing in imps, cacodemons, a baron of Hell and a pain elemental.

There are two more buttons in the north-west and south-east corners that need to be pressed, and will raise a set of steps leading up to the next floor where you can get a plasma gun; watch out for the imps that appear as you step on to the ledge. Go inside the brick tower in the north-west corner of the map and quickly kill the revenants that teleport in, along with the arch-vile and cacodemons that have appeared outside, then climb up the wooden poles in the tower to reach a walkway that leads to a rocket launcher and the red skull key. Watch out for the revenants that appear on the structure in front of you as you approach the key, as well as zombiemen and chaingunners teleporting in from the south.

Go back down to the floor below and proceed to the button on the south-east corner of the rock ledge, then press it to raise some steps up to the next floor and bring in imps, revenants and demons. Climb up to the next level then head north and west to the yellow skull key, ready to kill a revenant that rises from the floor to defend it, then go back inside the tower to avoid the mancubi and arachnotrons that ambush you. Go back up to where you found the red key and press the button here to lower it, then run straight forward (imps and shotgun guys will teleport in to block your progress) until you reach a pentagram switch with an "EXIT" sign; this switch will open the exit portal next to the starting point, but you will have to hold off a cyberdemon while you wait.

Other points of interest[edit]

Leaving the playable area by any means, such as an arch-vile jump, will activate an unseen crusher that drops on a voodoo doll and kills you. This will also happen if you jump up to the ledges with the yellow key and the exit switch before you have pressed the locked buttons that grant access to those ledges.

Secrets[edit]

  1. Stand on the walkway that held the red key and look north-east to see a button. Shoot it to lower a block in the north-west room with a megaarmor and a medikit. (sector 228)
