Secrets

 * 1) To reach the soul sphere in the southern cavern, jump to the small ledge with imps, then from there to the angled ledge with the rocket launcher. From there, follow the path of rockets up to the soul sphere. (sector 230)
 * 2) At the intersection where the crusher is located, go south and outside. In this area, instead of heading into the water, go along the trees and then make a jump to the dirt where the lone tree is. Through the window, you can spot a BFG9000. Shoot through this window to hear a door open. Now return to the starting point where the door is now open. Run across the bookshelves to reach the BFG9000. (sector 839)
 * 3) Along the wooden, winding hallway, you might hear a lift lower in the hallway. It is likely you will come across this lift while heading back from pressing the switch at the end of this path. Make sure to run quickly to this lift before it rises. Up here are lots of health and armor bonuses along a ledge overlooking the lava. To get the secret you need to go into the lava (there is a radiation suit in the northwest corner) and go all the way south. Lots of energy cells and a plasma rifle await here. (sector 1006)
 * 4) In the yellow key room, there is a skull switch at the northeast, just below the steps. Use it to open a room with a backpack and a box of ammo. (sector 1016)
 * 5) Past the first trap, turn left towards the yellow door and press the lion switch to the left of the door. A chainsaw, twenty shotgun shells, and three medikits are inside. (sector 1026)
 * 6) At the intersection where the crusher is located, go north. Before the door, open a wall to the right and use a lift to reach an invulnerability. (sector 1040)
