There is a readme with full(?) instructions on installing
First extract the .rar to a convenient place (then read the readme
).
Then copy the folder " spitfire_on_my_tail-part1 " (without the quotation marks) to //.......SteamApps/common/il-2 sturmovic cliffs of dover/parts/bob/mission/campaign/
While you are in this folder you need to add these lines to the campaigns config file.....
the folder "Cloud Free' contains alternative missions (with no clouds) for those with lesser rigs. If you need to use these copy the mission files over those above- (I recomend at least trying the cloud version first)
The campaign installation tool should work also
copy the "Skins" folder to // Documents/1C SoftClub/il2 sturmovic cliffs of dover/Paintschemes
