There was an original deal on Elite, which was a membership fee that included the map DLC's for MW3. Then they decided to make Elite free with no maps included and introduced the season pass for BO II. And that is how it has been ever since.
There are many videos of Elite, which show it's functions etc. Have a look at some and you will all be enlightened. It's a great app which sadly has been denied to the PC community. But now we are to recive it and enjoy it's great features too!!!
Sounds awesome. getting more excited for this on the pc by the day!
