single-player campaign
about how many hours can one get out of the single-player campaign?

well on your first play through pn normal difficulty Im guessing 8-10hours.
if you play again on hard you could get another 5 hours out of it.
Then if you play for achievments on the quick mission section you could add more hours.
You could stretch it out if you want to.
