Anyone have any other good sites for dark forces custom missions? Or can upload the missions that they have?
You could try the Wayback scrape of it here :
Or, better still, this 84mb archive has all the levels from the site. Any other tools or files you can probably get from the link above : https://archive.org/details/StarWarsDarkForcesLevels
For posterity, I downloaded literally everything from df-21.net, because it seems like that site goes down about every other month. So, if anyone ever needs any of the levels or editors from that site, here they are : http://www.mediafire.com/file/s2ra966nzo4q3x2/Dark_Forces_-_df-21.net_Downloads.zip/file
