Half-Life Hints

How do I open the glass doors that the scientist is standing behind?

  • 1 of 4: The glass is bullet-proof, so you cannot break through it.
  • 2 of 4: The scientist does not feel safe enough to let you in. As you know, aliens are lurking about.
  • 3 of 4: There are quite a few aliens in the computer room. Maybe if you killed them all, the scientist would have an easier time letting you in.
  • 4 of 4: Be sure that all aliens in the room have been destroyed. Once this happens, the scientist will open the doors. Listen to what he has to say.
