Secrets

 * 1) Head straight east from the starting point to the platform with the shotgun. Three compartments in the previous room will lower revealing monsters to kill. After getting rid of them, return to the platform and face southwest towards the blue compartment. There is a hidden skull switch that you can shoot here, which will raise some steps up to the southeast compartment. Take those steps up and use the lift to get a soul sphere. (sector 494)
 * 2) Look east and slightly southeast from Secret #1 towards the cage. There is a small shootable button on the wall. After shooting it, some health bonuses will teleport to the ground below. Follow them to the newly-formed staircase to the south. At the top, you will find a plasma gun. (sector 661)
 * 3) Northeast of the steps in Secret #2, if you went into the small room and flipped the switch, a new window will open up southeast of Secret #2. You can jump from the ledge where Secret #2 is and get some energy cells. (sector 633)
 * 4) In the open field with crates on the left side of the map, head to the caution stripes at the north end and face east. There is a glowing skull you can shoot. Shooting it reveals a teleporter in the middle, which takes you to this secret sector. (sector 2420)
 * 5) From Secret #4, use the switch in front of you, then head along the path going north and west. Near the boxes of rockets, you can climb the crates to get an energy cell pack. (sector 1868)
 * 6) Take the lift out of the nukage area at the north end of the map, then use the switch and climb the steps you see. Flip the switch at the top, then head southeast and towards the next switch. Look west and drop to a megaarmor. (sector 93)
 * 7) When you can, climb the curved staircase at the eastern end of the map. Head to the other end of the ledge here and flip the switch, then enter the passage to the southeast to the next switch, which will reveal a fiery area around the curved staircase. From the top of the stairs, you will have to make a well-timed strafejump to reach the fiery area, where you can then find shotgun shells and a soul sphere. (sector 1061)
 * 8) On the way to the blue key, you will climb some steps down to a big door. There will be a side room to your right. Go back up the steps and notice the terminals on the left wall. The middle one is glowing. If you shoot it (you have to shoot the screen, not the terminal itself), several skull switches appear in the side room. Of the five switches, the correct one is the second one from the right. The other switches summon monsters into the room. After hitting the correct switch, a switch behind the light will be revealed, which will lower the lift nearby and allow you access to the BFG9000. (sector 2327)
 * 9) Open the big door mentioned above and enter the next area, but quickly head back up the steps (if the door closes, you will need the blue key to reopen it). Return back to the high ledge and go to where the switch mentioned in Secret #7 is and jump through the nearby opening to the energy cell pack. (sector 1467)
 * 10) After using the switches in the red skull key room, go back outside and head north up the steps. Follow the marble path south, hugging the wall as you do. When you approach the window, notice the two brown stripes on the wall. Walk backwards past the lamp, looking at the stripe on the right side. If you look close, you will notice two skull eyes that show up for a brief second when you pass the lamp. When you shoot these eyes, another pair of skull eyes appears on the stripe to the left, except these are lower than the other set of eyes and will close off in three seconds. What you need to do is shoot the first set of eyes (which may take a few tries to get right), then quickly fall off the ledge and into the field nearby and shoot at the second set of eyes while facing southeast. Do it right, then return to the marble ledge and head into the next room. There will now be a hidden area with the Vargskelethor mushroom, three barons of Hell (Hell knights on Hey, Not Too Rough or lower), three energy cell packs, a megasphere, and a BFG9000. (sector 2612)
