Essentials[edit]

Approach the skull switch in front of you to lower two lifts with one or two chaingunners, then ride the right-hand (east) lift up and follow the passage to a berserk pack and super shotgun; you cannot reach the rocket launcher on the block yet. Continue east through a door with blue triangles and go round the corner to another door, which leads to a staircase with revenants and chaingunners, then climb to the top of the stairs to lower a small wall to the south, which you can use to reach the rocket launcher. Taking the weapon will open the wall in front of you to reveal a round room with a water trench, then drop into the trench and go to the south-east corner, which will open the eastern wall. Behind this wall is a room with ten brick columns, which will lower when you pass or interact with them and reveal various monsters; the eastern column holds an arch-vile as well as the red skull key, and taking the key will open the east wall and release some revenants. Entering the room will close a door behind you; to open it again, ride the column that held the red key up to the top to find a hidden button.

Go back to the starting point and walk to the south wall to lower the floor, kill one or two waiting chaingunners then step on another lift at the south end of the room to go down to a red door. Go through the door and follow the corridor to a round room with a tech column (a yellow barrier will close behind you), then press the column to lower it and get a plasma gun. Taking the weapon opens two compartments with chaingunners (or revenants on Hurt Me Plenty (HMP) skill level or higher) inside them—after killing them, go inside the eastern compartment and press the skull switch here to raise a step by the western window, which will allow you to run across a block with an evil eye and land in the open area below with four large buildings.

Open the door on the west side of the gray building to get inside (a Hell knight will be waiting here on HMP or higher), then use the lift in the south-west corner to go up to another door which will put you on a small ledge. Kill one or two mancubi waiting on the neighboring building then run across to their platform, then press the panel with blue triangles on the east wall to lower the floor and reveal a path. Follow the path to a lift and ride it up to a room with a megaarmor and berserk pack, kill the approaching revenant and cacodemons, then press the button in the middle of the room to open the path to the yellow key. Drop down to ground level and go to the wooden building at the north-west end, enter it then go east and south up the steps to a skull switch, which will lower a wall outside below a yellow door. Now collect the megasphere on the west side of the building, then run through the window next to it—as you fall you should land on another window just below, then on the platform with the yellow skull key.

Go to the marble building at the west end and use the silver lift at the south-west corner to go up to a yellow door, then interact with the door to open the building and reveal various monsters inside it. Press the skull switch inside the building to open the way to the exit, then go to the wooden wall on the east side of this area and press it to activate a lift that will take you back up to the overlook. Return to the starting point and press the skull switch to lower another lift, ride it up then go north into a cavern with mancubi and barons of Hell. Continue north up some steps to a megasphere, passing a white teleporter on the way, then collect the powerup to lower the wall ahead and reveal (depending on skill level) two arachnotrons, a spiderdemon or a cyberdemon. You do not have to fight these monsters, and can simply press the skull switch on the north wall to end the level.

Other points of interest[edit]

Use the left-hand (west) lift at the starting point to enter a hexagonal room with a megasphere, which is on a platform surrounded by a pit. Pressing the switch inside the pit lowers the platform, allowing you to reach the megasphere and open the surrounding rooms. When you reach the north-eastern room, you can press the tan wall at the north-east to lower it and get the blue skull key, along with a berserk pack and some large ammo pickups.

In the cavern just before the exit, you can go down the north-eastern steps to a small room with a skull switch and a megaarmor, among other items. Pressing the switch activates a crusher above the metal platform in the cavern, which will crush the barons there along with any other enemies that are caught under it. The white teleporter on the steps leading to the exit will send anything that touches it to the platform; this is especially useful on Ultra-Violence and Nightmare, as the cyberdemon guarding the exit can be lured into the teleporter to crush it.

Secrets[edit]

  1. Pressing the switch behind the blue door in the south-east area raises a bridge (which can be lowered by pressing either side) from the central platform to the south-west of this area. From the south-west platform, walk east across the ledge as far as possible to reach the south-east platform. Part of the wall has a lion head on it—this is a secret door, leading to a megasphere on a platform. (sector 50)
  2. In the south-west area of the map there are four buildings. From the southern ledge of the central building (from which the southern building is reachable by jumping), there is a lift in the center, leading up to a secret door, leading to a small room with two boxes of rockets. The eastern wall of this room is a secret door leading to a room with a health bonus. Taking it lowers two walls leading to a ledge with a supercharge. At the northern end of this ledge is a window that is actually a lift, leading to a room with some imps and one or more lost souls. The northern wall of this room contains a secret door leading to a platform with an energy cell pack. (sector 114)

Bugs[edit]

When you enter the passage leading to the yellow key area, a yellow barrier will close behind you, stopping you returning to the starting point until the yellow key has been collected. This barrier is locked on both sides with the yellow key. When playing a cooperative game, if you die after the barrier has closed and before you pick up the yellow key, you will respawn being unable to finish the map.
