How will Cross platform play work?

[Miuna]

So i never knew the release was planned for cross-play until a friend told me, basic research told me Microsoft planned it from the early days which is awesome, i played all Halo's growing up, my bro has a Xbox but i should would love to play with him again.
What i wanna know, how will crossplay work? So i will have steam and him xbox, will i need a xbox account? I have one but haven't used it in maybe 5-10 years now. Will it work like other games in creating a ID and having a ingame friends pannel to invite ID players? Looking forward to this and hearing reach has a date, its the start of a great journey!

Guess we will see for cross play. I have never read anywhere it was "planned" only that the team would like to bring it out IF it was possible. Not simple if your cross playing controller vs kb/mouse players it would only be fair if it matched players by peripherals. All we can do is wait and see.

Pretty sure they stated they were releasing with some cross-save functionality for campaign. Where checkpoints within missions would be synced to your Xbox Live account. So resuming from where you left off (on other platform, say to play with friends) would be easier and progress wouldn't be lost.

Cross-play will only be available between the Steam and Windows Store (PC) versions of the game:

Console Cross-play hasn't been confirmed yet, as far as i'm aware.

Within MCC, yes, your progress and progression will carry-over between the console and PC versions. All stats, achievements, Forged maps, and game variants will be shared between all of the games within MCC. Mid mission saves will be unique to each platform and cannot be shared.

For existing Halo: The Master Chief Collection owners on Xbox One, cross-progression support will be a welcome addition to avoid a fresh start. However, with cross-platform purchasing yet to be confirmed, players may need to re-buy the game once it hits PC. And for Halo: Reach veterans, your progress sadly won't transfer from the original Xbox 360 title.

one thing they are doing with reach is give us all the armor skins as a apology on the reach progression.
