The PlayerUnknown's Battleground Test Server (PTS) for Xbox One is once again live with a new update you can download right now. Update 18 makes several gameplay changes to the battle royale game, including dynamic weather effects and bullet limb penetration. The update will remain on the PTS for playtesting before being applied to the main PUBG servers at a later date.

So far, the Xbox One version of PUBG only includes the Erangel and Miramar map. PUBG Corp. hasn't announced whether weather effects will launch on Sanhok or the new snow map once both come to the console version of the game. Erangel is getting the Overcast weather condition, while Miramar is being updated with both Overcast and Sunset.
