Loved this game as a kid back when I got my first MS-DOS / Windows for Workgroups 3.11 PC back in 1994. Was only ever able to obtain the shareware version of this title back then, and longed to be able to afford the full version.
I was fortunate enough to later acquire the full version as well as a fix for the bug in the second mission as described in the stories told by some of the other fine folks regarding this game. Abandonware is your best friend in this case, should you be interested. (just Google "Abandonware zone 66")
Admittedly, I still play this game to this day trying to finish all the story missions.
Would be super awesome to see a polished, solidly presented version of this game by GoG. Here's to hoping this eventually happens one day...
