The Korean game rating board, GRAC, has inadvertently revealed the existence of a PS4 version of PlayerUnknown's Battlegrounds.
The Korean Game Rating and Administration Committee rated PUBG for 21 years and older, due to "excessive violence", drug use, blood, the inclusion of realistic weapons and other PUBG characteristics.
The rating, spotted by Nibel, was given on September 11. The page doesn't mention anything we don't already know, just that it's for the PS4 version.
PUBG Corp. never officially announced a PS4 port of PUBG to be in the works, but it never denied that the game could one day be available on Sony's console. The official message has always been that the team's focus is on finishing the Xbox One version.
Now that PUBG has hit version 1.0 on Xbox One, it's very possible work is underway to bring the game to PS4. While Sony does not have a system for early access games like Steam or Xbox, the publisher is happy to make exceptions for certain developers.
Earlier today, the same Korean board also outed Castlevania Requiem for PS4, a collection that includes both Symphony of the Night, and Rondo of Blood.
