Half-Life: Blue Shift Hints

How do I turn the steam in the catwalks-and-ladders area off?

  • 1 of 4: There are two spots with steam blocking your path.
  • 2 of 4: There are also two valve wheels (one on the lower level, one on the upper).
  • 3 of 4: Turn them both to clear both walkways of steam.
  • 4 of 4: Now you can follow the lower walkway to a room with a fun shotgun, and follow the upper walkway to a room with a very important button in it. Be sure to press it!
