Can someone please make a .fc2 file that lets me skip mission 13? It keeps crashing right at the end before I can jump out.
Where exactly is it crashing? If you're having trouble with the mission, reducing the difficulty level will make it much easier, but this certainly shouldn't be happening.
Which is why i decided to fly one 
So, question is now; Are the guys behind PI considering a sequel?
It's just me. You could say I'm considering it, but I don't really want to get started on anything unless I know I can commit enough time to see it to completion, which is looking unlikely at the moment.
The one mission i couldnt complete was the turrets mission against the saturn. Even though i took out 15, still said i failed.
You probably missed one somewhere that you thought you destroyed. I know the mission works fine in this respect. You get a message every time you get 5, 10, 15, etc.
I was originally planning to make an extra HUD gauge for that mission that would show exactly how many turret kills you racked up, but that required certain features of the scripting system that the 3.6.9 builds didn't support (and the HEAD builds that did support it had a lot of other bugs). I may be able to add that in an update when 3.6.10 comes out though.
