The campaign is terrible and the story uninteresting. The AI teammates are useless and show how rushed and horrible the coding was for the game. They can't pathfind the most simplicest routes and you'll die because of it. 343 really liked the idea of boss fights so much they force you to face the same boss a dozen times and taking a spark of creativity the way they introduce increasing difficulty for later encounters of the warden boss is by adding more copies of him in later encounters. I have never been so frustrated and irritated by a Halo campaign. Really makes you wonder if they studio even tried playing this steaming pile before full releasing it to the public.
