PlayerUnknown's Battlegrounds first arrived on Xbox One late last year with its release on the Xbox Game Preview program, and now the popular battle royale game has officially launched on Microsoft's console. PUBG's big 1.0 update is now available, bringing the title out of early access and introducing a slew of new content to it, including a third map, new weapons, and more.

The most significant addition is Sanhok, the tropical-themed map introduced in the PC version of PUBG earlier this year. Unlike the game's first two stages, Erangel and Miramar, Sanhok measures only 4km x 4km (as opposed to 8x8), making it much smaller than PUBG's previous maps. As a result, matches contested on Sanhok are much quicker and more intense than normal.
