It is possible to play CO OP between XBOX ONE FAT and XBOX SERIES S

Hello Alexxah5665! I'm Claus, an Independent Microsoft Community Consultant for Xbox! Glad to be able to help you!

No all Xbox One/Series X|S games have splitscreen co-op available. So, are you able to inform what game are you trying to play with that mode?

I have the same problem since yesterday between an Xbox One FAT that was the main one and a One S of my children, it seems that it is a worldwide problem.

Hello, first it's a pleasure to be able to help you today.

My name is welcome to the community.

Hello ChemicalSleep, are you referring to the Xbox One Fat console, or the Xbox One S?

I ask this because the only console that has the (power supply)external source is the Xbox One Fat (Original), the Xbox One S/X and Series S/X the source is internal, the only thing different is the cable.

And in the case of cable you can buy anyone who adapts to the console.

That simply means that you can play co-op with both local and network players in a group of between 2-4 players. It does not state that cross platform play is possible.

Hi there,

I'm not entirely sure, but since the game when purchased is playable on Xbox One and on the Series consoles, my assumption would be that since it is the 'same' item in the store that co-op would be possible too. Still an assumption though
