Half-Life: Blue Shift Hints

How do I get through the locked door on this little ledge I'm stuck on?

  • 1 of 4: Have you tried banging on it? That's what you, as Gordon Freeman, saw Calhoun do right near the beginning of Half-Life. (That's Gord that passes by you soon after you debark, you know.)
  • 2 of 4: You can't open the door from this side.
  • 3 of 4: But do push up against it and get a no-open noise at least once. That'll alert the guy on the other side that someone's out there.
  • 4 of 4: Just wait until he manages to open the door, then go on in.
