I own the Halo 4 Limited Edition and haven’t downloaded the Majestic Map Pack yet. Someone in my family is hogging the TV and couch and our internet is suffering through a variety of problems, so I can’t download now but I wanted to ask this question in advance.
Where do I go to download the Majestic Map Pack without being charged for it another time? Please try not to confuse me in your answer. 
Cheers!
