Recently I've discovered that a map beta I had released for closed community few years ago, isn't lost. I'm publishing it here just to show how it all was supposed to look like. To be honest, when I've re-discovered it and visited the map after years, I got impressed by my own work. The development ended sometime during late summer 2013 for performance reasons. The map can be played as "mod". I strongly recommend to use developer's flying mode to move around (F3). It's much faster. There are many secret and underground places that worth to find and visit.
