Secrets

 * 1) If you have the red key, open the red door near Secret #2 for a passage. (sector 91)
 * 2) On the leftmost side of the map, you may spot a rocket launcher and a partial invisibility on a high ledge. A switch near this high ledge opens a door above. Press this switch and press on the nearby wall with silver bars around it, which will reveal a demonic face. Now return up the step and back north, entering a vine-covered shack, then head up the steps to the new opening. By collecting both the rocket launcher and partial invisibility, the demonic face opens up and the ledge lowers. The area behind the demonic face with monsters and a megaarmor counts as the secret. (sector 192)
 * 3) The room containing the blue key has two switches near the key. Press the one on the right to open the cell on the left side of the nearby room, which contains a medikit and a box of rockets. A switch in here lowers the blue key platform. Make sure that when you press the right switch to open up the secret you do not press the left switch as well (this one opens Secret #4), as if you have not reached Secret #4 beforehand, then by entering this secret you will close off Secret #4 permanently and subsequently Secret #5 will be closed off as well. (sector 200)
 * 4) The room containing the blue key has two switches near the key. Press the one on the left to open the cell on the right side of the nearby room, which contains a medikit and a green armor. A switch in here lowers the blue key platform. Make sure that when you press the left switch to open up the secret you do not press the right switch as well (this one opens Secret #3), as if you have not reached Secret #3 beforehand, then by entering this secret you will close off Secret #3 permanently and subsequently Secret #5 will be closed off as well. (sector 209)
 * 5) To get the blue key, you need to press the switches in Secret #3 and #4 to raise a step and lower the blue key platform. Read the instructions for Secret #3 and #4 to ensure you will not miss out on this secret. (sector 244)
 * 6) If you have all three keys, continue down the passage mentioned in Secret #7 to a room with two armor bonuses and a stimpack. In this room, open the wall here to reveal cacodemons (plus a baron of Hell on Ultra-Violence or higher), a computer area map, a plasma gun, and a soul sphere. Where the computer area map is, you can walk through the wall with many faces to leave. (sector 286)
 * 7) If you have both the red and blue keys, follow the passage in Secret #1 all the way to the room with two backpacks and a rocket. The northern marble wall is a blue door revealing more of a passage. (sector 290)
 * 8) Right next to the exit switch, you can lower the wall to the south and walk through the spine to find a berserk pack and a chainsaw. (sector 328)
