Hmm...
May I suggest a little more elaborate story intro.
It doesn't build it up, and make people want and crave your campaign. I'd suggest some awesome writers I know 'round here to help you, but they're a bit busy with my stuff.
Also, it has been done to where the player is not in Alpha wing. Just so you know.
And don't get in over your head by planning 45+ missions either. That's A LOT of work (in case you haven't worked on a campaign to see for yourself). But if you think you can do it, more power to you!
Good luck!
