Halo 4 limited edition i'm confused.....

You get six early maps right?

some skins.

and you get a code for a season pass?

The code war games season pass right?

because i pre ordert it so i get the new maps for free.

You get the the three map packs (three maps in each) totalling in up to nine maps.
You get an Assault Rifle skin.
You get a Recruit armour skin.
The Season pass & code is the free three map packs.

Details of everything in the Limited Edition can be found here: Halo 4 Limited Edition | Halo Alpha | Fandom

You get six early specializations, as well as the season pass which will essentially give you the map packs for free when they are released.

you also get a 90 minute extended version of Halo: FUD

Don’t forget the tin case!

8 Specializations

What is that?
