  1. Go through the flooded section of the first hall, then when you go around the corner, lower the wall where the stimpack is to get a backpack. (sector 1214)
  2. In the huge outside area, head to the southwest side of the gray ground and behind a wall you will find a soul sphere. (sector 742)
  3. Go to the west side of the map and climb your way up to the red door. At the top, jump south from the rock to the grass below, then jump down from there to where an imp and a megaarmor are. (sector 1429)
  4. Lower the yellow bars at the north end of the factory, then head east to a switch. Go north from the switch and continue east, and at the end you will find an energy cell pack. (sector 1330)
  5. Open the red door and climb all the steps up to an area with two switches. Use the left one, then leave and head all the way back to the door at the south end of the factory where you entered the huge outside area. Open the door, then open the door that was at the bottom of the lift. There will be a new room open with a teleporter that takes you to a megasphere. (sector 1926)
