Doom/E3M6: Mt. Erebus

Walkthrough


On easy difficulty, you need to grab the blue key (located on the step of the green building on the north) and take the exit on the western side of the map (identified by a dulled nukage). On the harder difficulty, the trip is a bit longer.

You start on the south-east corner of the island, surrounded by a lava-colored floor, which damaged you. Your first step is a building on the north if the island, which you can reach by going through the building in front of you, or by running across the nukage on the right of the building.

The green building is rectangular shaped, and is a one-way door into the building. There is a berserk pack in the middle of the room. There is a candle on the sides of the room, which mark a concealed door. The left one leads to a teleport that brings you to the upper part of the map.

After the teleport, you should see two structures ahead of you. The right contains a chainsaw, and the left is a pit. You need to enter the pit to teleport into the northwest building.

In the north west building, there are two corridors. The right corridor opens the only exit from the building, while the left corridor contains the blue key within the harder difficulty levels. You will be attacked by Cacodemons from the northern windows.

Once you have the key, find a radiation suit or invulnerability. The left hand side of the map contains the exit, a small passage with a blue key door.

Features

 * The southeast building is visible from the starting position.
 * There is an ammo cache in the southwest corner, at the end of a path. Using the path to reach the ammo will cause the path to sink into the ground.  To avoid the trap, avoid the gap between the ammo and the pathway.
 * On the left hand side of the map, there is an invulnerability charge and a rocket launcher. There are several imps, demons and lost souls facing the launcher.
 * From the window of the first building, you can see a large C-shaped structure with green armor. Entering it opens two nearby structures, releasing more monsters but provides an invulnerability.
 * The north-east building is a one-way entrance. Entering the door drops you down, with Spectres flanking you from the side.  There are two teleports that lead outside, onto the ledge on the same building.
 * The north building is described in the walkthrough above.

Within the lava:


 * The southern building contains cacodemons, and is opened when entering the second floor in the first visible building.
 * The eastern structure contains monsters, but also a few items as well, including a radiation suit. When you first enter, a demon attacks, but immediately teleports to your left.  There are two switches in that room that open two doors containing the monsters and few items.
 * The close north-east structure is opened from the north-east building containing the two teleports. It contains a few cacodemons.
 * The farther north-east structure is opened by stepping on the front step of the northern building. It releases lost souls.
 * The north west structure facing the northern triangle contains cacodemons or lost souls. It is opened by running up and down the side steps in the northern building.  To prevent it from opening, avoid stepping up or down from the candle level.  However, it contains a supercharge and a radiation suit.
 * The northwest structure that overlooks the northwest building contains a computer map and radiation suit. The three cacodemons will attack as you try retrieving the key.
 * The western building next to the exit contains six cacodemons and a radiation suit. It is opened after leaving the northwest building.


 * the northern section is reached by a teleport from the northern building. If you fall down into the blue water, there's a teleport that returns you to the main section.

Secrets

 * 1) In the northeast building, take the right teleport to reach a plasma gun.
 * 2) In the northern building, open the right-hand secret marked by the candle.
 * 3) In the northern part of the map, run from the starting ledge onto the platform containing the chainsaw.  You can lock yourself out of this secret if you move directly to the teleport pit.
 * 4) From the northern part of the map, follow the ledge to the northern side.  You should see a switch enclosed by a wall.  Fire a rocket at the wall to propel yourself into this section, and flip the switch to reach the secret area.  Alternatively, you can try pressing use at the right angle against the outer walls to trigger the secret exit (but you won't claim the secret in the stats screen.)
