The campaign felt like it was really long, although it apparently wasn't for me since once I finished according to the game I spent a total of just about exactly four hours on it, which is quite different from the what I heard, which was it being 6 to 10 hours long depending how you played. And I played on Regular. I use rush tactics when I play usually, so I guess it works. I still think the campaign should have co-op.
