Here's the original thread with the outdated adventure map. http://forums.terraria.org/index.php?threads/the-legend-of-zelda-a-link-to-terraria-pre-1-2.1696/ You can watch the trailer and if you want to help test it or wait for the release later this week, is up to you.
I'd love to but I don't have the time for in-depth testing, reviewing. Glad to see you're still working on this!
