Secrets

 * 1) In the outside area at the north end, go to the switch that raises a bridge to the west, then head east and south from the switch. Go to the marble ledge with skulls, then hug the wall as you go west and up to a hole. Drop in to get ammo clips, a box of shotgun shells, and a medikit. (sector 358)
 * 2) In the starting area, climb the steps to the red switch at the south end and head east through a cave to find a backpack. (sector 446)
 * 3) Cross the rock bridge at the northeast lava area, then flip the switch at the end. Go back to the bridge, drop into the lava pit at the south end, then enter the west side before it closes. Use the wall, then as it rises, hug the west side to get a soul sphere. (sector 879)
 * 4) Flip the red switch at the start and the one behind it, then go east and look south at an opening. Drop into the lava from this opening and you will hear a door open. Run to the southwest corner of this area to find a lift leading to ammo clips, armor bonuses, and partial invisibility. (sector 899)
