Black Mirror II Hints

Open the safe.

  • 1 of 6: In the safe's close-up view, click on the five rotatable digits to see that they have letters on them instead of numbers.
  • 2 of 6: Exit the close-up view and look around for a clue as to what the five-letter combo might be.
  • 3 of 6: A ways to the right of the safe is a poster that you can examine.
  • 4 of 6: After you do, Darren will list several blood types in the order that's on the poster. (Note that it lies about type O being rare, but never mind that.)
  • 5 of 6: If you put the letters from the blood types listed in a row, you'll get ABBAO. That's five letters!
  • 6 of 6: Get the safe's close-up view back and enter those five letters. When they're all set right, the safe will open.
