Greetings all. I assume that I am doing something wrong, but "progression missions" seem to have dried up in my playthrough.
I've unlocked the significant majority of the tech tree, have ~ 4Bn in the bank and got 60% of the steam achievements. I have visited all of the planetary systems and at least orbited all of the bodies in the solar system. But, I only have 4 launch locations unlocked and for a long time now I've not seen any of the progression missions appear.
Are there some un-obvious missions that I need to be taking that will lead to progression missions?
Cheers
Ah, it seems the air race 1 was what I needed to do!
