Halo 4 WarGames Pass code

I have a code for the Halo4 WarGames Map Pack and each time i put RedeemCode on Xbox Live it says Invalid code. Can someone help me out here i want to play the map pack and use the armor but can´t because of this problem?

Where did you get the code? It usually says invalid code if it has either been entered wrong, or it has already been used.

From the Limited Edition.

Did you buy a pre-owned copy of the game? If so it is likely the code has already been used.

Also, by ‘armor’ I assume you mean the content that comes with the Map Pass? The ODST/Mark V etc armor is not part of this pack.

What Archellik said. But if it was a brand new, unopened copy, I suggest you contact Xbox Customer Support and explain your situation. They may be able to help you out in some way.

Yep a friend of mine buy me a Halo 4 limited edition for my bday. The game was closed so i know my friend didn´t use it. And yes i meant the pre-order content i only know that there is some map packs and the scanner and strider armor, but dont know what more. My problem is each time i try to input it on xbox com and it says invalid code, i havent try on the console yet, but if it doesnt work on the website less it will work on the xbox. I dont know what do you say… Sorry for the late respond i been busy lately.
