In th Limmited edition, Halo 4 War Games Map Pass is included.
The pass can also be bhought for $24.99 USD, it got Access to Nine Competitive Multiplayer Maps(Three Future War Games Map Packs, EachIncluding Three Maps)
But also, it says that it includes two helmets and one emblem:
In-Game Scanner Helmet
In-Game Strider Helmet
In-Game Falcon Emblem
Are these three in game items included with the Limmited edition itself?
I believe those items are used with the Map Pack itself. You get the map pack anyways in the LE, so if you are getting the LE you should be fine.
No you do not get the 2 Helmets, Emblem, with the Limited Edition War Games Season Pass. But you will if you buy the 25$ Xbox Live Marketplace Season Pass, they are different it would seem.
