Thanks to
Hallfiry's amazing
gaming magazine cover disk catalogue I was able to track down the elusive English Windows demo of the game (originally it was available from
Buka's website). The demo is uploaded here:

Note though that the zip archive is not original, as the demo files that I found are in the unpacked state on the
CD Action coverdisk #54.
