Master Chief Collection Co-op Failure

Why isn’t the Master Chief Collection letting me and my friends play together? No one can do the campaign together anymore. It was working fine the other day, but now it’s not working at all. We can’t get into the same party or playlist while in the game even though we’re in the group party through Xbox Live. It’s not our connection to the game because we can get into multiplayer just fine. The game just won’t let us play together for some reason, what’s going on?

This is getting ridiculous. It was working fine just a few days ago. It’s been a few days and it’s still not working. Does 343 pay attention to anything? How do I tell them what’s goin on so they can fix it?

Pardon my outburst, apparently it’s not just with Halo. This problem arises in some other games as well. Unfortunately it’s a Microsoft and Xbox issue as a whole. I understand they’re working on bigger projects and whatever, but they should still keep their current projects up to date and functional.

Hopefully everything comes together nicely.

Well…they got my account working right. Now my girlfriend is the one having issues with reverse compatibility

Anyone know how to unlock the CQB helmet?

I

I hear you unlock it just by beating the campaign on heroic, is that true?

For Halo Reach?
