MAP05: The Waste Tunnels (Doom II)

MAP05: The Waste Tunnels is the fifth map of Doom II. It was designed by American McGee and uses the music track "DOOM". If the game is played on Ultra-Violence or Nightmare! skill levels, the monster hell knight debuts in the map. Otherwise it will only debut on MAP06: The Crusher.

Essentials
The opening conditions of the level are dependent on the chosen skill level. On the two easiest ones, there is a shotgun at the gate in front of you. However, on the three hardest levels, a soul sphere can be seen in the distance, and the shotgun is replaced by a super shotgun.

Walk straight ahead at the start to enter a corridor. Beware the monsters that guard the area. Stay away from the walls, as there are several sinking platforms that can lead you to surprise encounters with imps that reside in small chambers below the floor. Head east towards the door at the end of the room. When you are at it, you will find out that the floor in front of it is a concealed platform as well. At this point, you are faced with a dark corridor with a three-way fork.

You have two alternative routes to the red keycard. The center path in the fork is the faster one. At the end of the path, there is a lift leading to a brick-floored hall. Go through the door on the northern side of the hall to get behind the barred area. Follow the corridor around to the east to reach the red keycard. Continue down the passage and drop into a network of water tunnels.

Go through the red door that is straight ahead. On Ultra-Violence or higher, you will face the first hell knight of the game. After defeating him, pick up the blue keycard, proceed through a second red door, and enter the adjacent blue door.

Behind the door, continue west or east around the wall. Then proceed along the edge to the yellow keycard. Upon picking it up, two walls will open up, revealing cacodemons. After dealing with them, you can go along the bridge and enter the yellow door to exit the level.

Other points of interest
In the starting corridor with the sinking platforms, the northwestern imp chamber holds a security armor. If you like to visit the place, move towards the wall between the two red torches using small movements. Such action will make the platform lower without you and expose the imps for you to kill. Get the armor and use the platform to return.

The northern path of the fork has a door and a blinking arrow pointing at it. Behind the door, there is a winding hallway with a soul sphere at its end. Notice that when you are at a hairpin turn, a room with a monster will be revealed in the direction you came from.

The southern path leads to a short hall with a series of doors. As you enter the new area, a door will close behind you, trapping you in temporarily unless you retreat rapidly. (Note that if you end up onto the side you came from, you can reopen the door by returning to the platform at the fork.) Each of the northern doors covers a room with a switch. The arrows on the floor indicate what the toggles will do.

The switch with the left-pointing arrow will open the door that prevented you from escaping. The one with the right-pointing arrow will open a chamber with a combat armor at the other end of the hall. The third switch with a down-pointing arrow will open a door at the back of the room that is opposite the switch. The opened route is connected to the aforementioned water tunnels. Face east in the area and go to the end of the watery passage. There is a staircase that leads to the brick-floored hall.

A certain section forms a rectangle in the water tunnels. The space in the middle can be accessed from the southern side. There is a room with a rocket launcher guarded by a group of zombiemen. If you yet enter the door to the west, you can get into the dry corridor behind the barred windows. The place holds a box of shells. On the three easiest skill levels, there is also a varying amount of medikits.

Secrets

 * 1) The corridor with the sinking platforms has a row of windows. Run through the easternmost window to reach a platform overlooking the outdoor area beyond. Upon entering the room next to the platform, a wall will open revealing some sergeants. After dealing with them, open the northern wall of the room to reaccess the corridor. Upon doing so, a floor will also lower at the far wall straight ahead of you. Quickly run into this hole to obtain the first plasma rifle in the game. (sector 94) Notice that you can also activate the two previous things by pressing the northern green torch in the room where the blue keycard is held.
 * 2) Once you have obtained the soul sphere at the end of the winding hallway, open the back wall of the alcove to reveal a berserk pack. (sector 92)
 * 3) When approaching the yellow keycard in the final room, two walls will open on the southern wall, releasing cacodemons. After dispensing with them, you can enter either of the two exposed holes (both lead to the same area) by running in from the higher platform. Inside are some imps and three ammunition packs. (sector 153)

Bugs

 * On Ultra-Violence or higher, two lost souls (things 107 and 108) occupy the same position and are immobile until one of them is killed.
 * If the player opens the westernmost door (sector 46) in the short hall with the series of doors while using no monsters mode, the ceilings of the combat armor chamber (4) and the alcoves to either side of the exit (153) will lower all the way to the floors, preventing the entrances into the rooms from ever opening. Due to an unknown reason, the two mentioned areas share tag number 9 with the westernmost door. They are thus activated as well when the door is opened, and since the ceiling heights of their adjacent sectors (the closed doors) are at the same level as their floors, the ceilings will actually move four units past the floors. During normal gameplay, it does not cause problems as the present monsters prevent the movement.
