Half-Life: Blue Shift Hints

How do I get past the "Security Clearance Level 04" door?

  • 1 of 7: Have you looked around for any security clearances?
  • 2 of 7: Have you tried making the door a little less secure?
  • 3 of 7: Like by knocking out its power source?
  • 4 of 7: Explore around, smashing boxes, until you find the room with the power box with the yellow warning sign above it.
  • 5 of 7: Either hit the power box with the crowbar or shoot it from a distance to blow it up.
  • 6 of 7: If you're too close, you might take a bit of damage, so I'd use the handgun.
  • 7 of 7: Then you can go open the security door with no trouble at all.
