Availability Is Not The Same As Cross-Play
A game can be available on more than one platform without letting players join the same lobby across those platforms. Check both the store page and official multiplayer notes.
Best Answer For Friend Groups
If your group wants to play together today, match everyone to the same confirmed platform first. Then check whether controller support and lobby size fit your plan.
Update This Page As Support Changes
Cross-platform information can change with patches. A guide page should record the latest official status and the date of the check.
