A PS4 release of PlayerUnknown’s Battlegrounds (PUBG) has been rated by the Korean Game Rating Board (as spotted by Eurogamer), indicating that its period of console exclusivity on the Xbox One may soon be coming to an end. Mobile versions of the game on iOS and Android released earlier in 2018.

PUBG is widely credited with sparking the battle royale genre’s explosion in popularity. At its peak, it had over 3 million people playing it concurrently as of January 2018. Other popular games have since joined the genre, including Battlefield V, Call of Duty, and, of course, Fortnite.

Will “Fix PUBG” make it to PS4?

After it was originally released on PC in March 2017, PUBG’s immense popularity meant that it was quickly snapped up by Microsoft, which published it in early access as a console exclusive in December of that year. As of July 2018, the game had reportedly sold 8 million copies on the console.

The game initially launched in a buggy state that saw its frame rate occasionally dip into the single figures on the console. While these performance issues are still being worked on, the game’s 1.0 release earlier in September saw it hit feature parity with its PC counterpart with three maps and dynamic weather now available for its console version.

It’s currently unclear what features and maps will be available with the initial release of the PS4 version of the game, which could receive a December release if Microsoft had a year of exclusivity. But hopefully the developer’s “Fix PUBG” campaign will lead to some quality-of-life improvements for the release.

This isn’t the first time that a Korean Media Ratings Board announcement has leaked for an upcoming game. Earlier this year, it heralded the arrival of Fortnite on the Nintendo Switch, prior to its official announcement at E3 in June.
