I was going to release my new map tomorrow to celebrate the 10th birthday of Quake, but since I will be away this weekend I decided to release it a day early instead.
You can find more information, screenshots and a download link over at my QExpo booth. You'll need an updated engine such as FitzQuake or aguirRe's enhanced GLQuake to run it, because it is about 50 edicts over the limit :(
