PlayerUnknown's Battlegrounds has received another post-launch PC update that targets cheaters, performance issues and its new incoming crate system. 

At the end of 2017, PUBG hit three million concurrent players and simultaneously announced it has banned 1.5 million cheaters since Early Access launch last March. The latest PC update—live now on test servers, coming soon to live servers—aims to level the playing field further still by allowing players to report others directly from the game's replay function.
