It appears that PLAYERUNKNOWN’S BATTLEGROUNDS for Xbox One has been unlocked in New Zealand, and the PUBG Xbox One download size has been revealed by the official Microsoft Store.

While we previously reported that the PUBG on Xbox One would require up to 30GB of free space, the official Microsoft store only mention a download size of 5.24GB for the game’s Game Preview that will release globally tomorrow. As said in our previous post however, the 30GB install size most likely refers to the game’s install size on Xbox One X.
