How can I open the doors in the hallways of New York?

  • 1 of 6: The doorways are controlled by some machinery.
  • 2 of 6: O'Toole showed you a similar machine in one of his transmissions.
  • 3 of 6: You'll find one in the avian city, and there are similar ones in the other two cities as well.
  • 4 of 6: Listen to the sounds that the machine makes when you move the piston.
  • 5 of 6: Each note corresponds to a single door.
  • 6 of 6: Move the piston to the location where it plays multiple notes.  Then, all the doors will be open, and you don't have to worry about those doors any more.
