The Mystery of the Nautilus Hints

How do I fix the gears?

  • 1 of 16: There is a fairly intricate meshing of gears in this room.
  • 2 of 16: Some are directly connected to each other, and others use a belt between gears.
  • 3 of 16: A couple of the gears seem to be loose -- apparently missing a bolt.
  • 4 of 16: You will need to locate some extra bolts, and secure the loose gears.
  • 5 of 16: The gears that are missing their bolts are not located on the bottom level of the Gears Room.
  • 6 of 16: They are located one level up from the floor.
  • 7 of 16: Look around on that level.
  • 8 of 16: Especially out on the walkway.
  • 9 of 16: Place a bolt on each of the gears there.
  • 10 of 16: There also seems to be a missing gear, as well as a missing belt, that you will need to replace.
  • 11 of 16: Both can be found somewhere in the Gears Room.
  • 12 of 16: Look on the main floor, at the bottom of the ladder.
  • 13 of 16: Take the belt and the extra gear up two levels within the Gears Room.
  • 14 of 16: Look around and see if you can tell where they might belong.
  • 15 of 16: Again, go out onto the walkway.
  • 16 of 16: Both the belt and the missing gear can be installed to the left of the walkway.
