PUBG Update 6.3 Adds New Weapon Balance Changes to Tommy Gun, M249 and UMP-45
By Max Mallow

PUBG Update 6.3 went live on test servers Wednesday incorporating balance changes to three weapons in the game.
PLAYERUNKNOWN'S BATTLEGROUNDS, much like most battle royale titles, require balance to ensure fair and competitive gameplay. While most were excited to see Karakin get a new exclusive weapon, others were happy to see balance changes to three weapons: the Tommy Gun, M249 and UMP-45.
After much teasing, the #Panzerfaust is now available on the test server! Try out the new weapon along side the rebalanced M249, Tommy Gun, and UMP-45!
