We're not EA customer service, but sometimes shedding a little light on silly stuff like this can help get results. More importantly, the news appears to be that some copies of Medal of Honor: Warfighter have gone out with cards that don't have proper download codes printed on them.
Those codes, as this card says, entitle the bearer to online play (without paying for the $10 online pass), admission to the Battlefield 4 Beta, and a map pack. Reader Doug A. bought a copy of Medal of Honor: Warfighter in New York this week and discovered that while his game had the card, the card didn't have a code.
We've reached out to a Medal of Honor representative about the codes issue. Looking through some of EA's forums there are scattered reports of codes not working, but not anything about missing codes altogether (like Ubisoft's screwup with the PC version of Rocksmith last week.)
