The Campaign is a true testament to the first game in the series but operations leave such a bad tast in the mouth that it has ruined the rest of the experience. The enemies are balance completely differently and way overtuned or your weapons are nerfed to crap. Either way, unless you want to only play the campaign it isn't worth the purchase.

Just play the first game again and enjoy your time.
