Co-op games in game pass

I would say Realm Royale it's not a local co-op but its fun to play. Astroneer has co-op online it's in Game Pass. There's Riverbond it has local live co-op.

Well, it's Official for me at least. EA destroyed a Game Franchise in the name of MP/ Co-op. Ten bucks says, it will have an Online Pass for Co-op.

Is there a way to filter co-op games when browsing Game Pass titles on the Xbox?

The Lego games are great for local co-op, I think The Lego Marvel game is on there. #IDARB is a lot of fun too, Human Fall Flat is brilliant for local co-op play. There's also a Bomberman game available on Game Pass.

There's a lot of games that are co-op on Xbox One right now. I'll link the list of Game Pass games that are co-op, then select filter, then co-op, and you will see a wide range of options. While this is a Game Pass list, it's a list of Xbox co-op games so
you won't need the Game Pass if you just choose to pick a game for you and your partner to buy. You can also find Free to play games that are co-op in the list.

One more option for your concern on huge updates and game maintanence. You can set your console and games to update automatically in the Xbox settings on your consoles. However, this means you will not be able to control storage space with each new update,
and you may go over data cap limits if your ISP limits your data.
