Secrets

 * 1) At the mixing plant near the center, fall into the brown sludge and down to get boxes of rockets and a computer area map. (sector 397)
 * 2) On the path leading to the yellow key, head into a small cave to the west and use the south wall to find a switch. Flip it and go to the yellow key room to find it has expanded, with shotgun shells and a soul sphere behind the key. (sector 526)
 * 3) In the mixing plant, get the shotgun shells in the water and quickly head west, just south of the steps to the north. Open the northwest wall and go on the west floor before it rises up. (sector 881)
 * 4) Ride Secret #3 up and head west to get a soul sphere. (sector 883)
