Duke Nukem 3D Hints

How do I open those orange force doors?

  • 1 of 8: No, those switches next to it don't deactivate the force fields -- they control each of the cell doors behind the force fields.
  • 2 of 8: First, make sure you've got the red card.
  • 3 of 8: Go into either of the doors on the compound that require the red card.
  • 4 of 8: Enter the rotating room (hit the switch to get in) and then shoot the switch again to make the room rotate.
  • 5 of 8: Notice that you can now reach two doors.
  • 6 of 8: Go through each of the doors and look around.
  • 7 of 8: Switches in those two rooms deactivate those force fields.
  • 8 of 8: You can use the security screens to check on the status of the fields.
