I’m not really sure what to make of this, but I bet some of you would.
I was googling some Black Mesa level design tips (I find written descriptions easier to work from than digging into other maps), and I found a completely unused, neglected Black Mesa Level Creation page on the Valve Developer Community site. It has the same basic section layout as all other Source game level design pages, but it doesn’t actually have any pages.
I’m an amateur at mapping, but I have it on pretty good authority that a lot of you guys, for lack of a better term, know your shit. I bet a lot of people could make use of that page if it had some well-written, descriptive content.
That, or it could use deletion, considering it looks like its creator doesn’t, well, exist anymore.
Still, I think a level design wiki could bring a lot of people into creating community content.
