Secrets

 * 1) Follow the trail of health bonuses until it curves left. Keep going and climb the steps, then head east until you reach the edge. Turn north and follow the ledge in that direction to cause a wall to lower. There will be an arch-vile (not on Hey, Not Too Rough or lower) guarding a switch and a rocket launcher (or a box of rockets on Hurt Me Plenty or higher). (sector 83)
 * 2) Follow the trail of health bonuses until it curves left. When it does, head right and down the steps, then just head north of the steps where you will find an imp and a stimpack. If you look south from the stimpack, you will find a hidden switch. Shoot it and go east to the wall, turning south to find medikits and shotgun shells (there will be a box of rockets on Ultra-Violence or higher instead of shotgun shells). (sector 727)
 * 3) Picking up the purple key causes some walls to lower, two of them are far to the south where revenants will attack you. Go to the area where they came from, then get onto the high ledge to the left. As you do, a lift lowers. Quickly drop off to the east then down the steps to the east, then quickly turn back west and into the alley to the left of the steps, then south to the computer area map. (sector 742)
 * 4) Go towards the red keycard, then look west and you should spot a purple garden with health bonuses and energy cells. (sector 602)
 * 5) Just south of where Secret #4 is, move a bit to the left and look north to spot a target switch hidden behind purple grass. Shoot it and head east, then south, then east again to trigger a lift. Take it up, then head to the south wall and turn east, entering the teleporter to reach a secret area with a BFG9000. Note that the sector with the energy cells next to where you teleport counts as the actual secret, as the BFG9000 becomes available later on. (sector 159)
 * 6) After you get the red key, head back to the top of the lift in the previous secret and head west to the red switch. This will lower the wall allowing you to reach the previous areas again. Now head all the way back to your starting point, where a switch will be revealed across the fence. Quickly run back to where this switch is and flip it before it closes, doing so will lower a wall to the south. Follow this corridor back to the starting area to reveal another switch to the west, which will lower the yellow keycard. (sector 253)
 * 7) With the yellow key from the previous secret, backtrack to the switch in Secret #1 and use it. Now backtrack to the area east of where the purple keycard was to find the switch block has been removed. After flipping the next switch block, fight off the enemies until the switch block lowers, then keep dropping down until you hit the bottom. The next switch block will net you the BFG9000. (sector 753)
 * 8) After you pick up the red key, return to the purple gardens near the center of the map and use the red switch. Drop into the lava below and quickly leave to the north. There is a green button here that will lower the metal ridges, allowing you to collect various supplies. (sector 121)
 * 9) In the same area as the previous secret, get to the southeast corner and use the switch, then go to the northeast corner and use the lift. As it rises, face west and shoot at the purple grating. At the top of the lift, use the switch to the west to trigger a lift below, then head southwest to that lift and ride it up. At the top, if you had shot the purple wall before, there will be an opening to the east, allowing you to drop down to the red armor. (sector 313)
