Lord knows if anyone still cares about the thing but heres some more screens. I'll get a playable version out once I fix up some holes I created redoing some areas (not pictured).
I'm working on adding nodes for npc usage too. I'll get that out with the other updates. The small list I can think of are on the site. Email me with any comments/suggestions you may have.
/edit I found some embarrasing holes just now. I'll get a new version up in a few mins
/edit 2 Ok mostly fixed theres an hole in one of the tunnels caused by a nodraw brush penetrating into the world brush. But I couldn't be bothered doing another compile for such a small problem (it's not that noticeable)
