Interesting that they call their service UDS. I was under the impression that they used PlayFab.

MCC probably has an "interesting" architecture as it's a combination of Halo games that spans a few generations that makes something like playfab a bit too restrictive to work in.

Halo Master Chief Collection was already released for 4 years (2014) when MSFT bought PlayFab (2018)
