Halo MCC and DLCs?

I'm getting this from trying to Install the "Halo Nightfall" DLC that comes with the MCC.

Hi, do you own the master MCC on xbox with a digital copy or a physic (on DVD) one?

I honestly did not heard about the fact that the MCC will be free for PC players who already own the xbox version, but note that the campaign of Halo reach is not included in the base MCC but it is available as a standalone DLC for 10$, so even if if you
own the MCC you will not be able to play the single player of halo reach if you do not buy the DLC, you can also play it with an active subscription of the game pass since they have included the complete MCC with reach and ODST in it.

Thanks for contacting us my name is Samy, I am advisor independent and I will be helping you today.

How are you, mate?

These 2 games are DLC's for Halo MCC, you have to purchase and install Halo MCC to be able to access this content in-game.

DLC mechanics in the works for Halo: MCC, then?

Probably good for the franchise, though I hope they can clean up the multiple menu navigations before adding more Halo material to the collection.

Hello chrisgerrad1,

Thank you for contacting the Xbox Support forums. To confirm, you had purchased Halo Master Chief Collection but you are only seeing Halo Combat Evolved. Before we try to assist further, can you please confirm that you see Halo Master Chief Collection as a recent purchase through the Microsoft Store? You can do this by following the steps here: View Purchase History.

If you see Halo Master Chief Collection, we may try to assist further. It is possible that there may have been an error in the transaction and may have only purchased Halo Combat Evolved.

I look forward to your response,
