Secrets

 * 1) In the central building is a circular blood pool in front of a Baron-faced wall. Follow the stairway to the left up, and continue along the path and down another set of stairs. At the bottom of the stairs, do a u-turn left and you'll be at a doorway leading outside. You should see a gray brick "railing" surrounding the lower pathway outside. Run onto the top of the railing from the doorway you're standing in and turn around. There is an alcove in the wall just left of the doorway you came from; run into it from the railing to get the megasphere and BFG9000 inside.
