We'll unlock the first planes for sale after the next mission, including but not limited to; the F-16, Mirage 2000-5, the F-20A Tigershark, the F-4G Wild Weasel, the A-6E and of course, all the starter planes will be readily available for very low prices. Prices will be around Ace Combat level, but made higher so each plane is truly an investment, not just a thing you can jump into for one mission then abandon.
Also available will be many other non combat related items. I'm keeping it secret for the moment, but if you're well-versed in anime and gaming, you may get a laugh out of some of the references. There'll also be food. Lots of food.
