Half-Life Hints
How do I get past steam-shooting pipes?
1 of 3: All of the pipes that have steam flowing through them, whether they are on or off, have flow control wheels nearby.
2 of 3: Locate the flow control wheel and turn it to cut the flow of steam through the pipe. The pipe will be safe to pass by.
3 of 3: Steam-shooting pipes can be used against aliens as well.
