"Not currently available

Hello dear Gamer, first it's a pleasure to be able to help you today.

My name is Vinicius.

I am a gamer and independent advisor on the XBOX community platform.

Hey AmelHalilovic, how are you today? Hope you're well.

So, there's an outage going on, on the gamepass services, it might be some instability, because Skyrim is available on gamepass PC, console and cloud. :/

Try to wait for a while before installing again.

And about Halo, I believe you're installing the MCC indeed.

I believe you will have to install the whole MCC.

It just means it's not available for purchase currently. Doesn't look like they have a specific release date for it yet so it wouldn't be available for preorder yet.

Hello, how are you? My name is Mateus. I'm an Independent Advisor and I'll be glad to help you today.

First, welcome to the Xbox community. I believe this may be due to the purchase region you are in, maybe the additional content of this game is not available for her, however, I suggest that you read the article below for possible solutions.

*Thank you in advance for contacting, I hope this can help you.

Yes, gamepass is going through some instabilities right now. Your welcome mate, needing any help, count on us. Have a great day, cheers.

It would be best to contact the developer of the game or post on their forums/official pages to provide feedback concerning this matter.
