I just noticed that there was no archive of Blueyondergames’s QW movie directory was online anymore so I re-uploaded it to https://www.quaddicted.com/files/mirrors/gamefiles.blueyonder.co.uk/blueyondergames/trailers/movies/quakeworld/
Have fun!
PS: You can get a full archive of their FTP tree from 2014 at https://archive.org/details/gamefiles.blueyonder.co.uk thanks to a fellow Archive Team superstar.
