You’ll get to learn about folks from both Gearbox and 2K, and how each person who touches the game both influences and is influenced by Borderlands 4. This week, we're talking with Philip Hebert, Gearbox’s Principal Programmer:[/p][p][/p][p]How do you define your role as a Principal Programmer? In other words, what does it mean to you beyond seniority?[/p][p]Philip:  Gearbox defines a Principal Programmer as a person with a deep mastery of at least one specialty. This usually comes with seniority but is not a requirement.  I have worked on gameplay systems, specifically gear, on a majority of Borderlands games.[/p][p][/p][p]How do you make sure engineering decisions empower (not limit) art and design teams?[/p][p]Philip: Borderlands' gameplay systems are designed to be flexible and content-driven.  We also learn from previous games.  This may mean removing the ability to do things because of performance and creating new and better ways of doing them.[/p][p]
[/p][h2]Community Creative Corner[/h2][p]Our community members aren’t just gamers—many of you are also artists. Whether it’s cosplay, digital art, or some yet-to-be-invented medium, we’re your biggest fans. Check out this week’s hand-picked fan creations:[/p][p]
deepestloverducknerd[/p][p][/p][p]EVR//DFT[/p][p][/p][p]dry_spacee[/p][p][/p][p][/p][p]That’s it for this week—with more updates, more chaos, and maybe a few surprises coming next Friday. Until then: keep your ECHOnet tuned and your loot luck high.[/p][p][/p][p]Happy Hunting,

Don't panic, the new Borderlands 4 update's boss farming nerf was an accident and Gearbox is reversing it

Nerf day has arrived, but it's landed a little too strong. The long-awaited Borderlands 4 patch notes Gearbox has been promising for weeks are finally here, just in time for the Horrors of Kairos Halloween event. They're largely focused on dealing with some of the "unintended interactions" that were leading ludicrous damage scaling and boss-melting builds, although there are some buffs and performance improvements to be found. But Gearbox has already confirmed that one of the most disappointing changes, one halting the ability to speed-farm bosses for big loot drops, was unintentional and will be reversed.
