PlayerUnknown's Battlegrounds on Xbox One has garnered a large playerbase since its release, but content-wise it still only features one map. Developer PUBG Corp. announced today at PAX East that this will change in May, when the studio adds Miramar, the desert map that has already been available for PC players for a few months.

PUBG Corp has revealed that the desert map, called Miramar, will come to the Xbox One version of the game next month. Right now, only the original map Erangel is playable. The studio hasn't provided a specific release date yet for the map, although it promises that more info will be announced soon. In the meantime, a new Xbox One update is coming.
