About the x360 sunset

I’ve been farming the online achievements on x360 halo games for some time now, and I was wondering what the “empty tiles” mean in the chart they posted here:

Sunsetting Halo Xbox 360 Game Services in 2021 | Halo News | Halo - Official Site (halowaypoint.com)

Im worried if ill be able to get the h3 ODST achievements and also the CE anniversary ones after they sunset the service, could someone here explain?

Thanks in advance, and sorry for any english mistake (not my native language)

As far as I know they’re just taking down online support, so it should only affect multiplayer achievements. All campaign stuff should still be doable.

Except Vidmaster Challenges.

I think that all the achievements you have to make in matchmaking will not be unlockable after the closing of the servers.
