Other points of interest[edit]


  1. In the computer room at the east side, get to the high floor, then on the southernmost ledge. Inch to the south wall as much as possible without falling and press use to open a wall. Hop over to it to reach a computer area map and a switch. (sector 160)
  2. After using the switch in Secret #1, go back through the winding hallway and south to where the sawed-off was. The pedestal it was on has lowered. Walk over this pedestal to open the walls to the south, leading to a rocket launcher and rockets. (sector 256)
  3. Open the yellow door and shoot the wall with the warning label for a radiation suit. (sector 397)
  4. Once you open up the southeast teleporter in the starting room, enter it, then open the south wall. On this balcony you can get a green armor, ammo, an NFG, and a soul sphere. (sector 358)
  5. See Secret #4. (sector 381)
  6. Lower the lift leading to the red key and get on its north side. To get this secret, you need to jump to the window as the lift rises, which can actually be tough to do. When you go through the window, the wall ahead opens, with health bonuses, a backpack, and partial invisibility. (sector 281)
