Great campaign, I really enjoyed it and I personally thought the ending was perfect.
However, while playing it I may have found a bug.
The mission "Into the Fire" does not finish properly if I fly a badger or a thunderbolt (I suspect anything other than the Nial) It gets to the part where I am sitting dead in space waiting to be rescued and gives me all the dialog, but it never moves on to the debriefing. After letting it sit for about 20 minutes each time I used the escape menu o return to the main menu and "continue" the campaign. Which of course started me over at the command briefing prior to "Into the Fire". It worked fine when I went ahead and used the Nial.
