Other points of interest[edit]


  1. In the forest, dive into the river at the west end and surface into a cave with a soul sphere and a megaarmor. (sector 31)
  2. Go through the vent system at the east side and go west at the second fork. Before the next fork, shoot the south wall to find ammo and partial invisibility. (sector 1236)
  3. After you get the green key, open the door labeled "PIPEROOM" and shoot the stealth imp, which will blow the barricade up. The pipe room contains medikits, rockets, and an energy cell pack. (sector 100)
  4. At the higher floor in the northwesternmost room, shoot all the terminals and you will notice that one of them will not break. Use it and enter the right column to get a computer area map, partial invisibility, and a backpack. (sector 1235)
  5. You need to destroy every single monitor wall in the level in order to get the super secret. After you shoot them all, you will get a message indicating that you have unlocked the super secret, which is in the middle of the base, just northwest of the station entrance. This room has the author's initials, a megaarmor, a soul sphere, and ammo. (sector 1238)
