For most PlayerUnknown's Battlegrounds players, finding an assault rifle is the happy-go-lucky moment when they realize their chances for survival just went up exponentially. That gleeful feeling will be going away soon, however, once the next PUBG update goes into place. According to the latest Steam notes, the patch will balance weapons in terms of damage and provide players with the solace that, even if not finding/using an AR, their damage output will feel just as powerful.
Players will also have more weapon attachments to choose from that, once again, "provide you with a wider array of attachment options so you can choose one that best fits your combat situation (rather than any one "best attachment")".
Lastly, level three helmets are considered by the team as "a game-changing item" that provides players with an extra life when headshot damage is taken. Because of this, the helmet is being removed from normal loot spawn tables and it will be found only in care packages.
