How does PUBG Mobile work?
Player Unknown’s Battlegrounds (PUBG) is now available on iPhones, iPads, and Android devices in the US, and it’s way cooler than a mobile game should be.

That is to say; it’s the same crazy-addictive, nerve-wracking 100-player survival deathmatch as the Windows PC and Xbox versions. It also has an online co-op for up to four players and voice chat, and it has many new features that make the game even better.
