In Battlefield 6, cross-platform online is an "optional feature", so PS5 and XBX|S console players can maintain a pure hosting experience without worrying about possible plug-ins intrusions on the PC platform.
Battlefield Studios gives this feature a new term: "Preferred Crossplay"
If you search for a game, it will prioritize matching you with players on the selected platform, and if no suitable match is found, it will expand the search to players on other platforms - it will only expand to cross-platform lobbies if there are insufficient players on the same platform.
If you only want to play with players on the same platform, you can also disable cross-platform games.If you play games on PS5 or XBX|S but don't want to play with PC players (and vice versa), you can create stricter search parameters.
PC players will match between Steam, Epic and EA App.In addition to cross-platform, Battlefield 6 also supports cross-platform progress, which means that as long as you use the same EA account, your progress and unlocking will continue to all platforms.
