Great news - Gog have finally sorted the rights and have got SS2 up on Gog! Tomorrow though, so you'll have to wait.|
Looks like it'll be a good version too - supports mods, has the soundtrack, maps of Von Braun to name but a few features
Even though I've still got it on disk, I've got to get this version!
RPS have an article on it
