PlayerUnknown's Battlegrounds Mobile's new update adds War Mode, an achievement system, exclusive skins, and more to the game. The update arrives for the mobile title a month after a first-person perspective mode was added in June.

PUBG Mobile is based on the PUBG for Xbox One and PC. The game features the same type of online battle royale gameplay where players parachute onto a battlefield and scavenge for weapons and vehicles in order to be the last combatant standing, but PUBG's controls have been slightly tweaked for PUBG Mobile to work with a touch screen interface. Like the Xbox One version of PUBG, PUBG Mobile currently only has the two maps Erangel and Miramar.
