Playerunknown's Battlegrounds launched on Xbox One last week in the Game Preview program and it was a quick hit. Playerunknown himself, Brendan Greene, said on Twitter that the game reached 1 million players on Xbox One after just two days. The game has not been without its issues on Xbox One, which is to be expected given the game is in an unfinished state. Greene said players can expect continuous updates for PUBG to improve and expand on the game going forward. After all, developer Bluehole is treating PUBG as a games-as-a-service title, so this kind of support is to be expected.

"This is humbling, so thank you all!" Greene said of the 1 million player milestone. "It's the start of the road on console for us," Greeene said. "We've lots to improve & update over the coming months & w/ your feedback we'll make a great game together!"
