The Limited Edition includes a code to unlock MORE specializations early. You still have to reach level 50, then can choose a specialization to level up.
I think you should post your issue here: http://www.343industries.org/forum/topic/16384-server-issues-bugs-errors-post-them-here-community-info-topic/.
I personally haven't had any further issues, nor my friends. 343i will be continuing investigations on the issue, so hopefully everything will be okay for you soon, good luck.
I believe the specializations are unlocked once you have reached level 50. The Limited Edition allows more specializations to choose from earlier than standard edition.
For me, it says "Specializations, skins, emblem, map pk." The maps will be released as three seperate map packs after launch each containing three maps. So yes, your map pack pass is included in the armor and specializations code.
Hi Ryno,
If you pre-ordered online, they tend to email the user the code on the release date. If you have not received your code within' 48 hours, I suggest you contact them. You should also check your junk/spam folder incase it was sent there by mistake.
Hope this post helped.
Hi Crayonmuffin,
The code you entered is the correct one. This includes a pass to download 3 future map packs for free, but not early.
Hope this post helped.
