Why can’t I choose the specialization that I want to choose? I only have two choices which are Wetwork and Operator, but the other 6 are just not there, and I’m a level 50. So why won’t Pathfinder show up on the list of specialization that I can choose from?
You don’t have a Limited Edition code entered.
You cant choose out of all the specs until the 20th so just choose w/e now and when the 20th comes you will get the other 6 unlocked and able to choose from
And the codes for unlocking them if you don’t have LE don’t roll out until the 30th. Sorry, but you’re lucky that the whole get all six others thing rolled out earlier than expected as is. Lots of LE buyers are angry about it.
if you didn’t purchase the limited edition of the game you only have access to 2 of the specializations 'til the 20th (i think that’s the date, could be wrong)
you didnt pay for limited it’s simple you dont get the extra ones till the 20th
This must be a glitch, seeing as how everyone who accessed Halo 4 multiplayer by November 20th should have access to all 8 specializations. I recommended posting in the “Issues being investigated” thread detailing the situation, although I’m sure they already know of this issue.
I’m a little worried myself, I’m not level 50 yet and I don’t know if that matters, but I can only see 2 of the specializations as well 
Only the limited edition has all the specializations available form day one. Early adopters of the standard edition should have them all unlocked in the next 2 weeks or so. Just hold tight and be happy you didn’t wait until Christmas to get the game.
You will get access to them ON the 20th if you have played not before
Because 343i is terrible at marketing. They’re making such poor choices!
if you ask me this is bull -Yoink- i mean a code what the -Yoink- has halo come to i mean -Yoink- this -Yoink- and the people that made halo need a wake up call big time every game a play has lag im level 90 and can not pick any more specializations and they wounder why ever man and his do have gone to black ops 2 that game is a peaces of -Yoink- but at least it dose not lag
