Battlefield 3, but you've gotta stop – at least, until EA fixes a problem associated with it. There's a glitch lurking out there, preventing Battlelog from recognizing progression and stats. It's like you never even played that last match.
According to the Battlefield 3 Facebook account, if anybody is using a FAMAS in any given match it's possible that no stats will be recognized – for any players. Best to table that firearm until this bug's number is up.
