I'm trying it on medium, and I get absolutely creamed on chapter eight when the big carrier ships come and release whole waves of small enemies. I have five or six laser turrets, one fighter bay making three fighters, and the main gun is upgraded to the point where it would cost 300-400 dollars to upgrade any more.
Is there a way to upgrade your ship's HP? When I start getting shot, my health drops awfully fast.
