Developer PUBG Corp. continues to fine tune PlayerUnknown's Battlegrounds on PC. On top of the forthcoming map select feature and new Codename: Savage map, the studio is working on an assortment of balance adjustments for weapons and attachments.

While PUBG Corp. didn't outline exactly which weapons will see tweaks and to what extent they'll be changed, it seems the balance adjustments will be wide-reaching. The reason for these changes, PUBG Corp. says, is to further level the playing field and ensure that no specific weapon feels "objectively better" than the others.
