PUBG Mobile is the localized version of PUBG: Battlefield, one of two mobile versions of the game that was previously only available in China, and very closely resembles the PC and Xbox One versions of the game.
The other version, Army Attack, is a more arcade-y, vehicle-heavy version of the game and is currently only available in China.
PUBG Mobile is currently not available in every region, but it has at least made its way to the U.S. I played a round on my iPhone 7 and it ran just fine.
Following a successful beta test in Canada, PlayerUnknown’s Battlegrounds Mobile just got a surprise localized international release for iOS and Android.
