KKND: Krush Kill 'N Destroy

this game isnt for sell any more i canot buy and its saying its in my library of gog.com but the odd thing is i only have the extreme and the KKND2
but not the plain version of KKND: Krush Kill 'N Destroy
plus the ingame unit editor doesnt really work becausse i have tried it out in extreme

Here on this page KKND is advertised as a DOS game. But on GOG who now owns the rights to the game, it says the game is only playable on Windows. Though I am sure there are ways of playing the game on other formats, why is it advertised as DOS here and Windows there? Why not just move this whole add (which is what it is, an advertisement for GOG) to the Windows download section since GOG only sells the game on that platform?
