A second round of Erangel loot rebalances has been made, as well as improvements to some sounds and effects related to gameplay.

Erangel Second Loot Rebalance

As we have spoken previously in our Dev Letter: Erangel Loot Rebalance, we are constantly analyzing player feedback, play patterns and other data. With this update, we're implementing a second round of changes to improve the player looting experience on Erangel.

  • The total amount of items spawned in Erangel has been increased by approximately 28 percent.
  • Increased the overall amount of items spawned, especially the spawn rates of those higher priority items.
    • Spawn rate of AR has been increased by approx 64 percent.
    • Spawn rate of DMR has been increased by approx 114 percent.
    • Spawn rate of SR has been increased by approx 177 percent.
    • Spawn rates of equipment and armor have been slightly increased, especially level 2.
    • Spawn rates of healing items have been slightly increased.

Erangel Blue Zone Rebalance Test (TEST SERVER ONLY)

  • During this test server phase, we'll be testing some changes to the blue zone on Erangel. At this stage, these changes are purely experimental and we're looking for feedback to understand how players feel about the direction of the changes.
  • There is no expected date or certainty that these changes will come to live servers, but we greatly appreciate and are looking forward to your feedback as we experiment with the blue zone changes specifically on the test server this week.

SR Damage Multiplier Changes

  • Decreased the damage modifier of SR shots to the torso from 150 percent to 130 percent.
  • Decreased the base damage of the AWM from 120 to 105.
    • The AWM will no-longer kill full health players wearing a level 2 vest in one shot with these changes.

Sound Improvements

  • We've now added more sounds for item interactions.
    • Previously items were looted, dropped, equipped and unequipped, some items had the same sound effects regardless of the characteristics of each item. Sounds will now vary more between items.

The main feature for PUBG update 28 is its Weapon Mastery system. In short, the suite offers small charms and medals as cosmetic attachments for solid performance with specific guns. Not only is the concept a cool way for skilled players to show off their achievements, but the visuals also help other players identify the most dangerous competitors on the map. If you see a high-level sniper charm in the fray, for example, you're best off keeping distance minimal to maintain a tactical advantage. Progression in battle royale games is generally kind of thin, but Weapon Mastery is a pretty cool idea nonetheless.

On the smaller end of the spectrum, PUBG update 28 features plenty of quality-of-life tweaks too. For example, the store UI offers better previews, it's easier to find guns on Erangel and a handful of troublesome Survivor Pass challenges are much more bearable than before. Update 28 certainly doesn't reinvent the wheel, but it adds a nice assortment of features designed to please the dedicated player base still involved with the game.

PUBG is available now on PC, Xbox One, PS4 and mobile. Update 28 is exclusive to PC Test Servers and will likely migrate to live sometime next week.
