The Xbox One version of PlayerUnknown's Battlegrounds got an update earlier today that included squad mode to gameplay. This was one of the biggest overlooked additions that didn't come from the PC version when ported. The update also is supposed to resolve game crashing and reduce intermittent in-game lag, but that has yet to really be tested by players. Let us know if you see any changes in PUBG!
Xbox players, we will be deploying a patch at 3AM PST / 12PM CET to allow you to enjoy Squad mode in all the ways possible.
You will now be able to play Squad mode as a 1, 2, or 3-man squad without having to matchmake with other players.
