How can I open the big wooden doors near the refinery machine?
  • 1 of 6: Examine the doors.
  • 2 of 6: They have several bolts stuck in them on one side.
  • 3 of 6: The bolts are what's keeping the doors up.
  • 4 of 6: Use all the bolts in order to remove them.
  • 5 of 6: Then the door will fall over, and you can get by.
  • 6 of 6: If you're on the wrong side of the door, you can't unbolt and open it. The way to get to the bolted side is to do the "Find the cave-in" quest and follow the tunnel past the cave-in along until you reach the bolted side of the doors.
