I was wondering if on of your friends has a PC copy of the game on Steam and I have a copy of the game on the Xbox Game Pass. Will we still be able to play together?

Also can Game Pass players play MCC:Reach with users playing on Xbox?
I think what you can play with the people of the Microsoft Store. But there is no crossplay
So people who share the Game Pass i.e. PC or Xbox, can play together? But those with Steam / Game Pass on PC can't?

That seems such a shame.

Other way around. People with steam and Microsoft store/game pass can play together, but as of right now PC and Xbox cannot play together. They may bring it in the future, but it is NOT in active development at the moment.
