  1. Drop into the water south of the yellow key tower and enter the red teleporter. From here you can get a soul sphere, a box of rockets, and a green armor. (sector 393)
  2. Climb the steps near the helipad, then use the left railing to jump to the east, on the wall with the yellow switch. From here, jump east to the rocks and follow them to the one with energy cell packs and a plasma gun. (sector 403)
  3. Flip the yellow switch to open the base, then enter. Press on the terminal immediately to your left when you enter, then quickly climb the nearby steps to the ledge. Run all the way to the opposite end of this ledge and enter the alcove before it closes. Use the switch here to find a secret room with a megasphere. (sector 1024)
