Map of Mountain of Sacrifice

Letters in italics refer to marked spots on the map. Sector, thing, and linedef numbers in boldface are secrets which count toward the end-of-level tally.

Essentials

The follower is facing away from you. Attack it will cause up to two more to drop down.

You will also be introduced to floor mines. Shoot them, and they will explode. They will not react to enemies, only you. Proceed through the tunnel, to reach a small canyon. Jump down, head to the right, fight the enemies, and flip the switch to open the bars blocking the north. Proceed past these open bars, and fight the two Hunters and Phage. Collect the green key.

Return to the canyon, and approach the north wall. Open the green key door, and enter. Defeat the creatures and flip the switch on the far end of the room, opening an alcove to the west. You may now get the minigun from the lift. Proceed north east, and into the room to the north. Take the north east exit, and follow the corridor to reach the yellow key. If you decide to go through the wall on the east, you will go through an arena, where you fight a gauntlet of Phages and other enemies.

With the yellow key, head west from the chapel room. After jumping down, open the door on the right to head outside to the west. Stand on the floor switch to lower the bridge, and head to the second canyon. This leads to a small prison; flip the switch on the south to unlock the western portion of the map.

Head to the south-west part of the map. First is the main control room, which overlooks a sub. Exit, and head to the alternate control room to the west, and flip the switch to lower the purple key. Use this key to unlock the south-east door in the canyon.

Once you are past the final locked door, you should come across a small arena of Phages. step on the center floor button and head north. The exit is the ladder into the floor.

Secrets

1. After getting the green key and going through the green door, there is a central alcove to the east that opens after you press the switch in the northern part of the room. Look for a hidden door in the northeastern corner of that alcove and it will lead you to a platform where you killed a bunch of enemies earlier. (sector 73)
2. In the northern part of the map, you should see some prison cells. In one of them, there is a small candle in a wall alcove with a floor marking. Press it to open the northern wall, revealing a grenade launcher, armor, and a shortcut to the previous area. (sector 522)
3. At the western part of the map, you should be in a control room with a pillar in the northeastern corner. Press the blinking lamp on the eastern wall to lower the pillar, revealing super armor. (sector 145)

Bugs

In version 1.1, a phage (thing 363) is partially stuck inside a rock and cannot move. This was fixed for the Doom Classic Unity port.
