[quote]I can't find a way to unlock the fire team; I'm trying to play with my brother, but I can't invite him, or even he can't invite me. We both play on Xbox; he has the OG Xbox VCR, and I have the Series S. Also, we don't have a game pass; I thought it was not required for vanilla/campaign missions. Could that be the issue? Also, most of the videos or information online about opening the fire team are from the old Xbox dashboard using the friends app.[/quote] I think you need gamepass now. I remember a post from few weeks back with an xbox user mentioning that you need it.
