Mostly it is gameplay in the form of a completely new arena. An arena where WWII historical scenarios are run 24/7. It will be 100% mission based, and if you go off mission you could lose points. If you lose too many points, you are demoted. If you are demoted too much, you lose access to the arena and have to go back thru basic training (probably a bunch of missions with you versus the AI computer).
You just cannot join an escort bomber mission, then go off and chase fighters around instead of actually escorting the bombers. If a lot of those bombers get shot down, you lose points. You could shoot as many fighters down as you want, and it won't mean a thing. How many bombers come home alive is what counts in that one. If most of them come home alive, you gain points towards a promotion.
Not all machines are available to anybody. In the Battle of Britain, low ranking players can only fly Hurricanes. Only ranking players can fly Spitfires.
Again, it is all mission based. There is no spawing alone and going off to do whatever you want.
