Borderlands 4 Update Adds Halloween Event And More

by

Borderlands 4 just received a major update with improvements to gameplay and several fixes. It also introduces a spooky, limited-time Halloween event called Horrors of Kairos. During the event, players can unlock two new powerful weapons: the Legendary Order Grenade and the Legendary Tediore Assault Rifle.

Get ready for double the trouble during the Horrors of Kairos event! Defeat World Bosses for a chance to win two new, powerful Legendary weapons: the Skully grenade and the Murmur assault rifle. The event wraps up on November 6th.

From October 23rd to November 6th, players can participate in the free event, Horrors of Kairos. During boss battles, the game will even change the weather to a dramatic “blood rain.” By defeating these powerful bosses, players have the opportunity to earn unique Legendary weapons, and Gearbox has detailed the abilities of each one.

  • “Murmur” Legendary Tediore Assault Rifle: Executes weakened enemies with guaranteed crits on targets under 35% health
  • “Skully” Legendary Order Grenade: This deadly grenade fires projectiles as it seeks out the nearest target

So, Gearbox just dropped some update notes, and they’re telling us PC players with NVIDIA GeForce cards to update our drivers. They said the new version, 581.57 – which came out on October 14th – fixes a bunch of GPU crashes. Basically, they’re trying to stop our graphics cards from, well, crashing the game, which is always a good thing!

The latest US video game sales figures for September 2025 show that Borderlands 4 had the biggest launch in the series’ history. With these numbers, the entire Borderlands franchise is nearing 100 million copies sold, and Borderlands 4 is estimated to need just 6 million more sales to hit that impressive total.

The first downloadable content for Borderlands 4 will be available on November 20th. Unfortunately, the version of Borderlands 4 for the upcoming Switch 2 console has been delayed with no new release date announced. You can find a full list of game updates and fixes below.

Vault Hunter Changes

Harlowe the Gravitar

  • Addressed some Gravitar builds that reportedly caused performance slowdowns; they should no longer prevent UI elements from updating or Fight For Your Life sequences from completing
  • Gravitar passive and Augment bonuses to Gun Damage now correctly apply to Ripper Heavy Weapon barrels and the Ripper Legendary Heavy Weapon Steamer; Entanglement interactions also function as designed
  • Gravitar class mods have been adjusted to no longer roll +5 Pencils Down and push passives past their intended cap

Creative Bursts

Balance Adjustments:

  • Neutron Capture now converts all Gun Damage into radiation, and now only applies to Gun Shots, and not all instances of Gun Damage.

We’ve adjusted how Neutron Capture affects damage. Previously, it was scaling too strongly with all gun damage, beyond what we intended. This update keeps Neutron Capture as a top-tier damage boost, but brings its power level in line with our expectations. Because all gun damage now converts to Radiation damage, players will have more ways to increase their damage output through builds and benefit more from improvements to gun damage.

Cosmic Brilliance – Passive

  • Flux Generator + Annihilation interaction updated so spawned grenades now scale correctly with character level

Amon the Forgeknight

  • Shield visuals adjusted for improved clarity in combat situations

Trait – Forgeskill

  • Adjusted interaction with Forge Master class mod so Forgeskill now respects its cooldown in multiplayer

Onslaughter – Calamity

  • Camera behavior stabilized when combining Onslaughter with Order Legendary Pistol Noisy Cricket
  • Attack frequency of Rocket Punch is now consistent in multiplayer

Balance Adjustments

  • Seeing Red Duration restored no longer increases per point invested, and is now 4 seconds for all ranks.

We designed the ‘Seeing Red’ ability to be very powerful when used effectively, but also challenging to keep up. We’re not reducing its overall strength, but we are making it more difficult to sustain the effect.

Scourge – Vengeance

  • Scorched Kairos passive now displays consistent magazine size values for the Ordnance gadget
  • The Forgewave no longer fires unintentionally during Glacial Rapture
  • Projectiles no longer get stuck in the air when Forgemaster Firewall is active during the Fortress Indomita boss fight
  • Blackout Shock Damage now properly scales with points invested
  • Blackout is now 15% per point, down from 21% per point

We adjusted Blackout slightly after fixing how damage over time effects scale. While this is a minor change, Blackout will still be significantly stronger overall now that the damage over time is working as intended.

Crucible – Cybernetics

  • Visuals corrected so Forgeknight Forgeaxe no longer disappears when activating Crucible at the same time as throwing with Double-Edge
  • Corrected animation of Crucible while climbing
  • Raging Inferno Incendiary Damage now properly scales with points invested
  • Vex the Siren
  • Challenge “Me, Myself, Myself, and I.” now tracks correctly in multiplayer, independent of clone duration on other players
  • Dead Ringer – The Fourth Seal
  • Specter’s copied weapon now displays proper visual effects when firing with a Maliwan Element Switcher
  • Incarnate – Vexcalation
  • Bleed from Bloodletter has been updated so it no longer recursively triggers itself, preventing unintended damage loops
  • Phase Phamiliar – Here Comes Trouble

Balance Adjustments

  • Double Trouble Illusion Damage Multiplier is now 75%, up from 50%
  • Double Trouble Illusion’s Duration is now 8 seconds, up from 5 seconds
  • Apex Beast Damage Dealt increase increased to 15% from 10% per stack of Unsealed
  • Rafa the Exo-Soldier
  • Free Grenade from Filantropo class mod now deals appropriate damage even when no grenade is equipped
  • People Person skill tree
  • Action Skills – APOPHIS Lance
  • APOPHIS Lance changed to penalize Gun Accuracy instead of Gun Handling, resulting in projectile speed being unaffected.
  • APOPHIS Lance now benefits from cooldown reduction effects

  • Addressed reports that swapping weapons with the Free Loader Enhancement on an Order weapon with a Ripper magazine would cause all weapons to not consume the accurate amount of ammo

Other Gear:

Hey everyone, just wanted to share what we’ve been tweaking. We’ve boosted how well gear that improves your melee damage and action skill damage actually works. Basically, we want builds focused on those things to feel stronger, but we also want a bunch of different gear pieces to be useful, so we’re spreading the power around a bit. Hopefully, this makes finding cool gear even more rewarding!

Rep Kits:

  • Hard Hitter now grants 50% Melee Damage Dealt, up from 40%

Specializations

Groundbreaker:

  • Groundbreaker now only stores Gun, Action Skill, and Ordnance damage.

We discovered a bug with the Groundbreaker skill that caused it to repeatedly increase damage, potentially leading to unlimited damage. We want the skill to remain powerful, but prevent it from scaling infinitely. We’ll be keeping a close eye on how this change affects melee-focused characters and will make additional adjustments if needed. Fixing this issue was essential so we can accurately assess the skill’s balance and consider further improvements.
