Good news, PC gamers: for the first time ever, PlayerUnknown's Battlegrounds has gone on sale on Steam. Between now and July 5, you can buy it for $20 / £18, which is 33% off the regular price of $30 / £27. The reason for the sale, PUBG Corp. says, is to celebrate the game hitting a new sales milestone.

All told, PUBG has sold 50 million copies worldwide on PC and Xbox One. If you include the free mobile version in the number count, there are now 400 million registered PUBG players around the globe, with an average of over 87 million people playing the game every day across all platforms.
