  1. At the north hall, head all the way to the east and open the south door. Head south, then go through the dark brick wall to get a green armor. You will also trigger a lift to the east, which has a teleporter. Get there and you will teleport to a medikit or a blue keycard depending on your skill level. Teleport from this counter and you will get a box of rockets and a rocket launcher (the latter does not appear on Ultra-Violence or higher). (sector 50)
  2. At the northwest end, open the red door and run to the middle of the hall. Use the switch on the east side, run back to the hall, and go into the area just to the right of the hall to get a backpack and partial invisibility. (sector 61)
  3. At the south hall, head all the way to the east and open the north door. Use the switch where the dark brick is to lower the floor to the south, then go through the west wall to get a soul sphere. (sector 77)
  4. In the same area, go through the east wall to get a medikit. (sector 78)
