Half-Life Hints

How do I make it across the weak pipe past the residue compression room?

  • 1 of 3: Use the strong pipe.
  • 2 of 3: Go as far as you can on the strong (left) pipe, then jump across to the weak pipe.
  • 3 of 3: You should end up past the weak spot, and can continue on to the sludge-stirring room (which I'm sure you can get across without help).
