Half-Life: Blue Shift Hints

How do I get past the big grinding things a little ways down the canal?

  • 1 of 4: You can't while they're intact.
  • 2 of 4: You need to go explore elsewhere first.
  • 3 of 4: Go do the catwalks-and-ladders area first, then go climb the big ladder that's in the shadows.
  • 4 of 4: You'll eventually be able to push a crate full of explosives into the canal, and it will damage the grinders for you so that you can swim safely past.
