Secrets

 * 1) In the room with the blue keycard, unlock the switch with the question mark in front of it. Leave the room and head to the east side of the building. Go through the wall there to get a health bonus, and when you attempt to leave, you will teleport to a secret area at the northeast end. (sector 148)
 * 2) Fall into the damaging sludge in the east side of the first area, then head to the switch at the east end. Flip it, then go slightly south of it and shoot the button to the west. This opens the area to the southeast with boxes of rockets. Another shootable switch is to the north here, which unlocks the northeast platforms. (sector 1133)
 * 3) In the southeast room of the first section with the blue keycard that teleports away, unlock the west window and go out of it, then drop off to the south while hugging the east wall. Follow the wall all the way to the east side, grabbing a health bonus and flipping a switch. Press the next switch to get this secret in a platforming segment. (sector 1462)
 * 4) Head to the large section of damaging sludge near the start, then head west and north into a cave. Flip the switch to lower the floor, then follow the path all the way to the super shotgun. When you rise up, get the megaarmor to the northeast. (sector 2541)
 * 5) In the platforming section at the northwest side of the map, make sure you have used the red and yellow key pedestals to raise the middle platforms. Head to the middle and head northeast and southwest to get the plates there, which leads to the northwest arena. (sector 3162)
 * 6) In the first area, head to the east side, use the north lift, then get up. Leave and go to the black platform to find a peg that leads to the platform. Stepping on the platform reveals a soul sphere. (sector 3314)
