Halo: CE Anniversary Backwards Compatibility Issue

I am trying to figure out how to play CO-OP Campaign on this game but on an Xbox One… I figured out that you have to hit ‘Y’ and change the network setting to ‘My Xbox 360 Console’ to see my second controller.

When I go to sign in a guest… it doesnt give me the option. Only my account (greyed out as its already signed in) and ‘Download Profile’ which I dont have another account to download. How do I add a guest that doesn’t have an xbox live profile?

343? Anyone?

Friend tried it to the same result :frowning:
