Okay, this is a harder quiz than the last one. These mid-school games (as I call them) are essentially the 2nd generation of arcade shmups. Be the first to ID all these ships and I'll put your name up in the soon-to-be-established Quiz Hall of Fame.
If you know them all, post a comment below. I won't publish any of the comments until someone gets all of them right so I don't give any away.
