My German is spotty (in the same way is my ability to fly by flapping my wings is "inconsistent"). Is this a 1C/official add-on, or some thirdy party campaigns, or a spoof?

I used google chrome ( auto translates) and I think it is 3rd party

Would be interested in more details. Seems like a lot of money for a campaign. With lots of meticulous research and uncompromising devotion to historical accuracy I can maybe see paying $43 for a campaign. Maybe.

With no sqd system its still just a series of missions.

Though it prob has some nice skins.

Seems to be 5 campaigns from desastersoft.

At the end it says, you need the German version of Cod, so maybe the mission objectives aren`t available in English?

It'll contain six campaigns (one Hurri campaign came on board late) and as far as I know they're definitely planning multilingual support.

Just be prepared, as i have learned in the demo, to fly real time sorties.
It is very reality based, if you don't keep the stukas, you are escorting in a mission, in view you might miss the enemy fighters attacking them.
So you return after 45 min. troubleless flying without sighting a enemy but having lost almost all stukas.
You also learn to close your radiators in cruise flight because the oil will go below 30°C in the 109 with open oil-cooler.
I found the missions very immersive!

Are they using the old IL2 voices?
