Your Halo Reach broke and you got Halo CEA. So you are at your best fried’s house playing Halo CEA after linking your account to his console. You have to leave and they ask if they can play on your guy without buying stuff and you need to give an okay. Then after getting home you go back on and after a couple of relinking problems you go on Halo CEA and you have all the DLC maps from Reach.It happened to me.
lucky you maybe he had the DLC and it somehow transferd it to your xbox
I dunno…
I guess it would be fair if the DLC you bought for Reach would interlink with CEA’s Reach multiplayer.
