PUBG Update 6.3: Panzerfaust Arrives as Weapons Are Rebalanced

PUBG Update 6.3 added a single-use Panzerfaust to Karakin and rebalanced the Tommy Gun, M249 and UMP-45. Here are the changes and the final loot plan.

PUBG Update 6.3 introduced the single-use Panzerfaust on Karakin and reworked the Tommy Gun, M249 and UMP-45. The patch notes were published on March 11, 2020; PUBG revised the M249 and DBS loot plan on March 13, and announced the update was live on March 18. The mechanics below describe Update 6.3 as released in 2020, not the current game rules.

How the Panzerfaust worked in Update 6.3

The Panzerfaust was a Karakin-exclusive weapon. PUBG described it as an uncommon world spawn and said it was guaranteed in every airdrop. It used a primary weapon slot and could be fired only once: after firing, the tube was discarded and could not be picked up again.

Blast, range and wall damage

The warhead exploded on impact, with a 6-meter damage radius. It could also detonate in midair if a bullet or explosion damaged it. Splash damage could pass through thin walls and objects for a short distance, and the weapon could breach specific Karakin walls, much like the Sticky Bomb.

The projectile could be dodged by an attentive player, as PUBG put it in the patch notes. The launcher offered zeroing at 60, 100 (the default) and 150 meters.

Backblast risk

Firing created a backblast danger zone extending 3 meters behind the launcher. It could hurt nearby teammates and pose a risk when firing close to a wall, so the space behind the weapon mattered as much as the target area.

What changed for the Tommy Gun, M249 and UMP-45

Weapon Update 6.3 changes Practical trade-off
Tommy Gun Added Red Dot and Holo sight compatibility; rate of fire rose from 700 to 750. Firing and moving accuracy improved, while the bullet-deviation penalty during sustained fire and extended-fire recoil were reduced. More sight choice and improved handling, especially during movement and longer bursts.
M249 Base bullet damage fell from 45 to 40 and recoil increased. Stock and magazine attachment slots were added. Standard capacity became 75 rounds, or 150 with an extended magazine. Lower damage and more recoil came with attachment flexibility and a move into ground loot.
UMP-45 Base bullet damage rose from 39 to 41; rate of fire increased from 650 to 670; muzzle velocity increased from 300 to 360. All three listed weapon figures moved upward, including projectile speed as represented by muzzle velocity.

The figures and changes in this table are the Update 6.3 patch-note values, not claims about later versions of PUBG.

The M249 and DBS loot plan changed before release

PUBG’s March 11 notes initially described the M249 as uncommon normal loot and the DBS as rare ground loot, both on all maps. On March 13, PUBG revised the plan after community feedback: both weapons would be uncommon ground loot on all maps, and the DBS would also leave Care Packages. The March 18 live announcement confirmed that the M249 and DBS had moved out of Care Packages into normal loot.

For the plan that ultimately shipped, the M249 and DBS were uncommon ground loot across maps; the earlier DBS rarity description was superseded.

Why Update 6.3 is historical context, not a current mechanics guide

PUBG’s Update 38.1 notes, dated October 14, 2025, record later Panzerfaust changes. They say a player wielding it cannot sprint, jump or vault; vehicle occupants take 20% less damage from a Panzerfaust hit, except for backblast damage; its sight-deployment sound is louder; and its trunk weight changed from 100 to 130. Those details belong to Update 38.1, not Update 6.3.
