My friends and I play it.
You sign up on their website then you start receiving emails for each scenario. I think it is one new map a month with several stories (war updates) while you wait for the next map.
You can then submit the results of the games you played with your friends directly on their website.
Please keep in mind that you do not have to use the same army that you declared when you registered, and you do not need to play the scenario that they email you. You can play any scenario as many times as you want. You can even play your own personal scenarios or games too.
It is a fun way to involve the players in shaping the world of Dust 1947.
I hope that helped :)
