There is a new beta up now, so everyone can get on the same page. No, there is no final maplist yet. We are still at the process where new things may happen at any time.
It is very advisable you read the readme.htm inside this zip, note that you extract the assets zips to their appropriate directory. Back up your current scripts directory if you already tweaked the originals, but these are the ones that are the working set for the distro. Unless I broke something. Then it won't.
This is a beta. It's barely that, and noone but the AI can connect to it, so it's single player only. That means don't waste your time starting a server and getting people to connect to it; it won't. They won't even realize they were kicked it happens so fast.

Plus for your enjoyment and something to waste your time, www.shadowspawn.net/temp/triggered_lights.zip is available to further entertain you with a non-documented "feature" of quake3 arena.
