Half-Life: Opposing Force Hints

How do I get past the purple laser that blocks the stairway?

  • 1 of 9: First, you have to get past the green laser by crouching and moving under it. (Also, keep right to avoid decapitation.)
  • 2 of 9: Read some of the signs on the wall.
  • 3 of 9: One of the signs warns that the mirrors are very fragile and should not be broken.
  • 4 of 9: Notice that the purple laser is being reflected by several mirrors.
  • 5 of 9: By breaking one of the mirrors, the laser might not be reflected across the stairway, and you could get out.
  • 6 of 9: One mirror in particular is quite fragile and can be broken. The others cannot.
  • 7 of 9: The circular mirror, the one that is the last mirror the laser hits before it is shot across the stairway, can be broken.
  • 8 of 9: Move up to the mirror carefully and use the pipe wrench on it.
  • 9 of 9: The entire laser system will self-destruct and you will be able to climb the stairs.
