Secrets[edit]

  1. In the blue key area, go to where the key is and jump out the window to the central platform. Press on the recessed wall there to find a computer area map. (sector 182)
  2. In the central room with the wooden block and the eye on top of it, take a lift up to the higher floor. To get this secret, you need to run towards this eye and get on top of the block, which will teleport you to the eastern part of the map. This area has a soul sphere. (sector 450)
  3. When you get to the big area at the southern part of the map, stay on the high ledge and head to the eastern part of the area where there are two tunnels with satyr switches on the sides. Press on the lit one to lower the floor, then head east to get a green armor, five armor bonuses, and a berserk pack. (sector 456)
  4. Now head to the western part of the area while staying on the high ledge. Go up the steps to a terminal and a yellow door. Use the terminal, then backtrack to the northwestern part of the map. A door with yellow bars is now open (it's near the red door). Take the lift behind it and you will eventually find shotgun shells, a medikit, and the yellow key. (sector 444)
  5. With the yellow key from Secret #4, return to the yellow door and open it to get a BFG9000 and energy cells. (sector 429)
