Walkthrough
The Cyber Demon taunts you throughout this level. At the first encounter, hit the switch to the left just inside the door to slam the door on him. At the second encounter, he will fight a Spider Mastermind for you. If you can't kill the Cyber Demon at this point, if you time it right you can step up onto the block he is on. The block will lower and once he steps outside that square he will be transported away.

In the yellow key courtyard, there is a hard to see 'X' switch on one of the bricks in the small rooms off the surrounding hallway. Hit this switch to open the pillar by the stairs. This will also spawn a Hell Knight. Hit the switch and head to the opposite side of the courtyard where the other pillar has opened to reveal a teleporter. Enter the teleport to be teleported into the central room, the round table. Hit the eye switch to smash a stained glass window at the end of one side of the surrounding hallway. This leads into a small courtyard with a soul sphere which you might have seen through windows while playing through the level. Above is an arachnotron. Entering the courtyard and defeat a Baron of Hell. Find the door and exit to the next level.
