Overview[edit]
This level is notable for being very difficult to gain 100% kills on at the end-of-level tally: In the room with the yellow keycard, the player must activate a switch to raise a small bridge to get a key. In the remaining pits on the left and right of said bridge are three deaf cyberdemons on each side, which the player does not have to kill to exit the level, but to gain 100% kills. If the player drops from the bridge the floor deals damage to them until they die, as there is no way out of the pits. All three keys are used.
Walkthrough[edit]
Essentials[edit]
From start you have to turn around and open the door behind you. There is a switch, which opens the doors in the east and west of the start area. First head to the east, where you find a large area made of red stone, go to the end and use the switch. This will raise the blood pools left and right from the bridge, and offer some stuff like the chainsaw, the rocket launcher and some ammunition.
There are two doors, one in the north, and one in the south. Go to the north door, where you will find the yellow keycard. This part is a bit tricky. After entering the room wait for the door to close behind you, then turn around and use the switch at the door. This will raise a small bridge, heading to the yellow keycard. Cross the bridge and get the key. Be careful, if you fall from the bridge, this will be the certain death for the player, because of the damaging floor and the three cyberdemons at both sides of the bridge. After you got the key, leave the red stone area and head to the room east of the start area.
Go down the stairs and take the path to north. There is a row of platforms lowering, after the last of them you find the yellow door. Behind the door lies the blue keycard, grab it and use the switch in front of you to lower the platform behind you. Now go back to the starting area and take the blue door.
Do not get fooled by the exit sign there, as this is not the exit. Behind the door you will just find the red keycard. Grab it, and go back to the area where you got the blue keycard, go down the stairs, and take the path to south.
Open the door and take the steps up to find the red door. Behind this is an area with toxic waste, and a switch on the opposite side of the area. Use this switch to open two doors to the east and to the west. First go to the short east hallway and use the switch inside to open the last door before the exit area.
Then follow the path after the western door, after a corner this will lead you to a dark room with three areas surrounded completely by walls. Jump over to the middle area, you cannot reach the outer area from there. If you fall down into the dark area, find one of two teleporters. Both teleport you into the middle area. At the end is the switch to exit the level.
Other points of interest[edit]
The door opposite to the path to the yellow keycard will lead you to a balcony from which you can see the exit area. There lies a plasma rifle. Right behind this door is a switch, which is hard to see. You can activate it if you stand directly under the door. This switch will raise the floor in the exit room, this way you can reach the areas right and left from the normal exit. Inside you will find some cells and the BFG9000.
In the room east of the starting area you find two little pits right and left from the stairs. The pit left from the stairs contains a supercharge, in the other pit you can find a blue armor. Drop into the pits to get these, at the bottom you find switches which raise the floor so you can leave the pits.
Killing the six cyberdemons in the area with the yellow keycard to gain 100% kills at the end-of-level tally is pretty hard, but not impossible. All six are deaf, so you have to get on the rising bridge before it reaches its peak, to let the cyberdemons see you. After that, you can kill them, but be careful, the only place to hide is in the small hallway at the entrance to this area, and you can open the door from this side only by crossing the line where the bridge begins.
Secrets[edit]
- In the area guiding to the red door, there is a hidden door in the north-west corner, right behind the backpack. Behind this door, you find a pit with a pillar inside. (sector 64) In the pit you find a chaingun and some ammunition. There is a small window, where you can open an entrance to the room behind. There you will find a computer map.
- In the hallway to the exit area is a small area at the corner. The wall behind the box of ammo and the box of rockets is a secret door to the second secret in this map. There you will find some ammunition and a supercharge. (sector 102)
