You'll be receiving a Halo 4 Red Avatar Suit as shown above - you may need to perform this tutorial multiple times to receive a "male" suit for your avatar as most codes you will receive are for "female" avatars. It took me a few shots to get a male avatar.

You should now see an avatar code. You need to redeem this on your Xbox console or Xbox.com - If you receive a FEMALE avatar suit and your avatar is MALE, please follow the tutorial again - it may take a few tries before you receive a MALE code.
