Secrets

 * 1) Enter the cave just northwest of the first temple area. Press on the slightly misaligned wall in the southeast corner to find a hidden passage. In this passage, go south a bit to a fork, then west and up to find an ammo stash guarded by a baron of Hell (on Ultra-Violence or higher), a Hell knight (on Hurt Me Plenty) or an imp (on Hey, Not Too Rough or lower). (sector 26)
 * 2) At the broken bridge where the yellow key is, grab a radiation suit and jump into the damaging sludge going southwest. There is a small opening you can sink in, follow this passage until you reach another radiation suit, a rocket launcher, a box of rockets, and a medikit. (sector 95)
 * 3) At the broken bridge where the yellow key is, there is a radiation suit to the east. Open the wall behind it for a hidden passage. (sector 220)
 * 4) From the hidden passage in the previous secret, when you reach the fork, turn north and go all the way northwest. When you get a box of ammo, push the wall to the west for a way out. (sector 81)
 * 5) From the hidden passage in Secret #3, go south at the fork. When you reach the dead end, open the wall to get shotgun shells and a soul sphere. (sector 244)
 * 6) From the previous secret, open the wall for another shortcut. You can also open this wall from the opposite end, just before the large rectangular room to the east. (sector 243)
 * 7) In the aforementioned rectangular room, push on a wall in the southwest corner and follow the passage up to a blur artifact. (sector 268)
 * 8) There is a misaligned rock wall north of the temple where the blue key is. Push on it to lower it and find a dark passage. (sector 264)
 * 9) At the end of the previous dark passage, press on the wall to open it, returning to the hidden passage accessible from Secret #3. Press the wall dead ahead for yet another hidden passage, and at the end will be a radiation suit and a light amplification visor. (sector 216)
 * 10) Open the blue door and go up the steps to the broken bridge. A misaligned wall is to the west, open it and follow the passage to a switch. Flipping it allows you to crush the mancubus in the cave. (sector 320)
