Conclusion:

This was by far the most enjoyable add-on campaign that my friends and I have played. The details to the maps are fantastic and the gameplay really flows along right to the end. Someone already mentioned that it feels like an official campaign and they were spot on. I don't really like the end much, but its not as bad as some of the above reviewers are saying
