PlayerUnknown's Battlegrounds has been $30 on Steam since its Early Access release in March of 2017. It didn't participate in any seasonal Steam sales, or run special promotions of its own. It never needed to, having sold millions of copies in just over a year, but for the first time ever, PUBG is 33 percent off on Steam, bringing it to $20 (or £18.08).

In the sale announcement post, PUBG Corp says that the game's combined Xbox and PC sales now total "over 50 million units worldwide." Include mobile players, and "over 87 million people play PUBG every day," it added.
