This massive mod by [SNF]Norbert adds 7 new clusters with 70 new star systems, new missions, new artifacts, bug fixes, you can now reach level 30, Flak Defense missions are easier, and much, much more. Way too much to list here. Norbert included an exhaustive list of every little change he's made in the changelog file, which is included with this mod.

All credit goes to [SNF]Norbert for this excellent mod that he's been working on for the last 12 years (!) and is still releasing updates for to this day. I just wanted to upload it here to make sure it's never lost, and hopefully so more people will find out about it. This is the definitive way to play DarkStar One, in my opinion.

Also keep in mind there will be some dialogue in German (mostly just with the new missions added with the mod), but they're pretty easy to understand if you've played the game before. Otherwise use a translation app on your phone, that's what I did. Google Translate lets you translate on the fly by pointing your camera at the text.
