Going into week two without campaign challenges. Hope they're not gone for good because without a Gold account, I don't have any other way to earn XP except for free play weekends like the one starting on this Thursday
EDIT: There is no free play weekend this month. For some reason, Xbox Live recently sent me a message for the 10/27/2016 free play weekend and I thought it was for this year. And this is right after experiencing the Microsoft Rewards' debacle of the buggy Points Crusader game earlier this month. Microsoft: still unbelievably sloppy after all these years.
