The excitement for Borderlands 4 is palpable, especially with the announcement of the much-anticipated endgame content. Building on the foundation of Borderlands 3’s Mayhem mode, which some players found frustrating, Gearbox aims to enhance player experience with features that cater to community feedback and introduce new mechanics. Here’s everything you need to know about the thrilling endgame in Borderlands 4.
All Endgame Features in Borderlands 4
During the PAX West presentation, Gearbox unveiled an impressive array of endgame features for Borderlands 4:
- Ultimate Vault Hunter Mode
- Pearlescent Loot
- Firmware System
- Specializations
- Weekly Missions
- Seasonal Mini-Events
- Invincible Bosses
Ultimate Vault Hunter Mode

Ultimate Vault Hunter Mode (UVHM) returns, functioning similarly to a New Game+ but with added complexity. Players will unlock UVHM after completing the campaign, allowing them to replay missions with enemies scaled up to match their level. These formidable foes boast enhanced health, increased damage, and special resistances, heightening the challenge and rewarding gameplay.
Why endure tougher challenges? The answer lies in the loot. Defeating these powered-up enemies grants valuable rewards, including increased currency in the form of Cash and Eridium. Borderlands 4’s UVHM features five sequential difficulty levels. Players must complete challenges across Kairos to unlock a final Wildcard Mission, filled with exceptionally difficult enemies. The good news? You can carry your gear into UVHM at an adjusted level, eliminating the need for tedious farming at the outset.
Pearlescent Loot
Fans of shiny loot will be thrilled with the return of Pearlescent items, set to drop in a free update during Q1 2026. Representing the rarest gear in the game, Pearlescent items are expected to be tied to UVHM. Gearbox describes their returns as incredibly rare, matching their power level with their sought-after status.
Firmware System
The new Firmware system introduces set bonuses to gear, adding layers to character builds. This system specifically applies to Repkits, Ordnance, Class Mods, Shields, and Enhancements. It consists of three tiers of bonuses:
- Minor – One piece of Firmware
- Major – Two pieces of the same Firmware
- Full – Three pieces of the same Firmware
Players can mix and match bonuses for unique effects, impacting stats like Ordnance damage or Action Skill cooldown rates. This feature unlocks after reaching level 25, with select Firmware sets exclusive to UVHM.
Specializations

Specializations enhance endgame character progression, akin to Badass Ranks from Borderlands 2 or Guardian Ranks from Borderlands 3. After finishing the campaign, players will unlock a Specialization XP bar for incremental buffs and skill choices. The skill tree starts with four basic nodes before branching into more advanced skills.
Weekly Missions
A structured weekly content schedule ensures vibrant gameplay in Borderlands 4. Players can expect free weekly events, including:
- Weekly Big Encore Boss
- Weekly Wildcard Mission
- Maurice’s Black Market Machine
Moxxi’s Big Encore Machine is a highlight, allowing players to farm bosses without constantly exiting the game. Each week features a tougher variant of an enemy, complete with a more rewarding loot pool. The Encore Boss and the Wildcard Mission have the same challenging traits for community collaboration, also guaranteeing a Legendary drop.
Don’t forget Maurice’s returning Black Market Vending Machine, making it easy to acquire Legendary items each week as its location will change.
Seasonal Mini-Events
Borderlands 4 also promises seasonal content, starting with the Horrors of Kairos event in October, offering new Legendary Weapons, Cosmetics, and a unique Weather Variant. More seasonal events are on the horizon, with details to follow.
Invincible Bosses

Finally, look out for Invincible Bosses, which will be released post-launch in Q4 2025 at no cost for all players. These fearsome adversaries come with formidable health, high damage output, and new mechanics, offering some of the best loot in the game.
