Does Halo Reach work online on Xbox One?

When I am connected to Xbox Live I am told that I need to purchase a map pack in order to play. Another issue is that when I connect on Xbox Live my character wears all the default armor with balck. Does anyone have the same problem? Is there a solution? I would love to try Halo Reach on Xbox Live because I never played it before.

i did for me and my friend a few months ago just had to re download all the preorder stuff separately…
that being said alot can happen in a few months…
