Other points of interest[edit]


  1. When you enter the main building, turn right upon ascending the steps (face west) to spot a shotgun. You can lower the pillar by pressing it to get this gun. (sector 52)
  2. When you reach the balcony above the courtyard, go to the southern end of this balcony and open the wall to the south. You will reveal a teleporter, allowing you to head inside the courtyard. There is a computer area map here, as well as health and armor bonuses and a switch. (sector 97)
  3. At the west end of the balcony mentioned above, you can find a teleporter which takes you to the blue door. Enter the teleporter, then teleport back. You will be standing on the first teleporter. Turn around (look north) and open the wall behind you to find lots of rockets and a rocket launcher. (sector 62)
  4. Exit Secret #3 and go to the long, green hallway to spot a newly-revealed teleporter to the east. Enter this teleporter to find a megaarmor. (sector 112)
  5. By flipping the switch in Secret #2, you will open up a hall at the north end of the long green hallway mentioned in the previous secret. This new hallway contains ammo clips, partial invisibility, health and armor bonuses, a box of shotgun shells, and a chainsaw. (sector 83)
  6. Once you teleport to the large cargo ship, go to the crate room (the central part of the ship) and use the small crates to get behind the large crate. Although there is nothing over here, you will trigger the last secret. (sector 623)
