Half-Life: Opposing Force Hints
How do I walk across the catwalk? Scalding hot steam is blocking my path.
1 of 7: Some broken pipes shoot off steam right down the center of the catwalk.
2 of 7: Therefore, there is no direct route along the catwalks that is safe.
3 of 7: Notice two things: First, one of the bursts of steam switches on and off. The other is constant.
4 of 7: And second, the catwalks consist of sort of a rigid S shape that corners out where the constant burst of steam crosses the path.
5 of 7: You can see the catwalk continue only a short distance from where the constant burst of steam is.
6 of 7: You could cut the corner if you jumped across where the inconsistent burst of steam spouts off.
7 of 7: Wait for the steam to shut down, then climb onto the railing and make your jump across to the rest of the catwalk.
