Secrets

 * 1) At the northwest part of the map inside the building, fall into the blood and get on the small platform in the middle. Use the east wall and run to the east side of the lift that lowers, then ride it up. At the top you will find boxes of rockets and a soul sphere. (sector 208)
 * 2) Head southeast from the large, barren area at the middle of the map. From here, head north to the stimpack, box of shotgun shells, and green armor. Press on the middle of the north wall and it will lower, revealing a secret passage. (sector 380)
 * 3) Inside the passage that is Secret #2, take a left at the first fork, then in the round corridor which blinks, head to the southwest side and open the inner wall to find boxes of rockets and a berserk pack. (sector 590)
 * 4) At the start, you will see a fountain of blood which has blood trickling onto the floor towards you. Enter the blood fountain from here and you will teleport all the way to the southeast area of the map, where you can get a plasma gun and a soul sphere. (sector 604)
 * 5) In the library at the northeast end of the map, climb the steps to the top, then head east past a light. As you do, hug the north wall while pressing use until a bookshelf lowers. When this happens, use the lift behind the bookshelf to find energy cell packs and a BFG9000. (sector 623)
