The developer’s new campaign, literally called “FIX PUBG,” is apparently a “months-long campaign to deliver the changes and improvements that [players have] been asking for”.
Looking at the Fix PUBG micro-site, the campaign is mainly about improving communication with players to inform them of fixes and improvements.
Some of these promises have already been fulfilled, as according to the PUBG community manager on Reddit, the bug-fixing campaign actually began last week with update 19.
Developer PUBG Corp has recently promised major improvements to the game, and it seems this time it’s really serious about it, as the company has set up a website specifically to allow players to track bug-fixing progress.
