be aware to download you must be registered
to that site.
As Poltava said, read readme about installation: in general you have to add a folder in Mission\Campaign\XX where XX is nationality (this should be US) where to dump zip content. Folder must be named as suggested by author. Also, if skins are included, those will be unzipped into Paintschemes folder of your main IL-2 directory. But, again, follow Readme instruction.
You will read name of campaign last added at bottom of list, scrolling in game "New
" Campaign Menu, after having set in same screen right nationality.
