I would suggest against turning them into a tunnel. Actually, I would advise against keeping it at all. If you listen to the Valve commentary, they talk a lot about keeping the level simple. If you look at something like dustbowl or goldrush, there's maybe an alternate path through the level, nothing more. I think it would be better if you removed the two rooms entirely, and put the healthpack somewhere more visible.Thanks, I was worried about it too. I made them when I was preparing the map to be converted to CP, but then went back and left them there. I'll turn them into a tunnel, that's what I'll do.
Just my 2 cents.
