Most people have. I haven't completed them all myself but meh. Too lazy :I
Oh I was being silly, I didn't complete those, but I don't think I could, either. Last time I really played, I was stuck in Campaign Hell mode with Quint and Keith's mission in the tundra, I think. That or it was Parker and Jessica's part on the ship... either way, I can't get much farther without dying like a wuss.
