E3M6: Mt. Erebus (Doom)


 * For the Heretic level of the same name, see E3M6: The Halls of Fear.

E3M6: Mt. Erebus is the sixth map of Inferno in Doom. It features a secret exit to E3M9: Warrens (and see the trivia).

Secrets

 * 1) Go inside the brown vine-covered building. Inside are two teleporters. Take the one on the right, and you'll be taken to a ledge with a plasma rifle on it.
 * 2) Enter the green marble building. There are two candles on the floor against opposite walls here. Open the wall behind the candle on the right for a bulk cell.
 * 3) From secret 2, open the wall behind the other candle and take the teleport. Once you're through, drop onto the platform ahead of you to get the chainsaw.
 * 4) Warning: this secret contains the secret exit switch and is inescapable, so only enter it once you are ready to exit the level. Pick up one of the invulnerability spheres from this level and make your way back through the teleporter from secret 2. This time, inch along the platform you arrive on to your right and around a corner. You'll see a blue box in the water below. Position yourself directly across from this box and face the red brick wall. Fire your rocket launcher at the wall and run backwards simultaneously, and you should be fired into the box, the invulnerability sphere absorbing all damage you would have taken. It's possible to straferun or jump (in some source ports) into the box, but the rocket jump is the intended (and easiest) method.

Trivia
According to John Romero, "The only way you are supposed to reach the secret switch [inside the blue box at the north end of the map] was by (1) getting the invincibility, (2) blasting a rocket into the wall so you would fly backwards into the box. We found out early on that it was possible to flip the switch from outside, so Sandy made the walls thicker." (See Doom Level History.) In fact, it is still possible to activate the switch from just outside of the walls, and also to straferun-jump into the box. See Access the secret exit on level E3M6 for details.
