Other points of interest[edit]


  1. Press the switch near the chaingun and return to the starting point. To the north of the starting point, jump across the red rocks to reach the super shotgun. (sector 406)
  2. On the west side of the map, approaching the ammo clips and box of shotgun shells lowers the rocks around you. Head to the lava to the north of those supplies, and then look east from the next set of supplies to find a switch. Use this switch, then head to the east side of this area and use the steps to backtrack to the super shotgun platform. You will find chaingunners and arachnotrons guarding a megaarmor. (sector 722)
  3. In the southernmost chamber, head to the southeast side and press the hidden skull switch in the chaingunner's closet, then go to the northwest corner and fall into the lava. Follow the path of stimpacks to reach a soul sphere. (sector 1681)
  4. Use the skull switch at the northeast corner of the map to access the steps leading to the central tower, but instead of taking those steps, go along the right side of the tower, going south and staying on the ledge, all the way until you find an energy cell pack. (sector 892)
