Secrets

 * 1) At the mixing plant near the center (behind the yellow doors), follow west from water into the brown sludge and drop down to get boxes of rockets and a computer area map. (sector 397)
 * 2) In the same area where Secret #1 is, get on a small platform with the shotgun shells on it that floats 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)
 * 3) Ride Secret #2 up and head west to get a soul sphere. (sector 883)
 * 4) 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 come back to the yellow key room to find it has expanded, with shotgun shells and a soul sphere behind the key. (sector 526)
