PUBG launched on Xbox One in the Game Preview program one month ago this week. After picking up 1 million players in its first 48 hours, the popular Battle Royale game reached more than 3 million players by the end of 2017, Microsoft announced today on the Xbox Wire.

The unfinished game is available for $30. Unlike other Game Preview titles, PUBG on Xbox One does not offer a free trial, which may have helped improve sales. If the three million players comes out to 3 million copies sold, at $30 apiece, that would amount to $90 million in revenue. It is unclear if this makes PUBG the most successful Game Preview game ever (others included Ark: Survival Evolved and Conan Exiles), though we suspect that might be the case.
