Half-Life: Blue Shift Hints

How do I return the system pressure to normal?

  • 1 of 5: Quickly go back up the control room's ladder and down the walkway to where the system pressure valve wheel is.
  • 2 of 5: It's right near the ladder that leads down to the main teleporter room.
  • 3 of 5: Face the wheel and lean on the Use key to crank the pressure needle back into the green zone.
  • 4 of 5: Some houndeyes will teleport in, so you may want to let the wheel go long enough to blast them, but get back to it as quickly as possible, and don't let up until the needle is on the far right of the green side.
  • 5 of 5: Now you can go back to the control room and wait for the need to press the big red button at the window.
