No, you cannot have local split-screen players AND online players in the same match on Xbox 360 / Xbox One / Series X|S. This limitation exists across virtually all games.
| Scenario | How |
|---|---|
| 2 players same console, same game | Local split-screen (offline or system-link/LAN) |
| 2+ players different consoles | Xbox Live / PSN / cross-play (each full screen) |
| Talk while playing different games | Xbox Party Chat / Discord (voice only) |
| Watch friend play | Xbox "Watch" feature / Share Play (PS) |
Workaround: If you have 2 local players and want to play with 2 online friends, run two consoles on same network—each runs split-screen, party up online.
