How can I recover lost DLC for Halo: MCC?

Hello DarkBoltex. I'm Arturo.

I'm sorry to hear you're not able to access to the Reach and the Halo 3: ODST DLC for Halo the Master Chief Collection. However, I'll be glad to provide some assistance regarding this matter.

In these situations, it is always a good idea to review if the account you want to use to play the missing contents is the one that under the licenses the missing DLCs are registered, DarkBoltex. So, I suggest you to review your Microsoft account order history in order to find the content listed there:

https://account.microsoft.com/billing/orders

If the content was purchased more than 3 months ago, please change the "ordered within" filter to "all available".

Are you able to see the DLCs listed there?

PS: Please avoid sharing the order number, or any kind of personal information, DarkBoltex.

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.

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.

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.

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