Borderlands 4 Bounty Pack 1: Mercenary Day, Invincible Bosses, and More

Gearbox has officially lifted the curtain on Borderlands 4: Bounty Pack 1 – How Rush Saved Mercenary Day, marking the game’s first major seasonal DLC event. The studio describes these Bounty Packs as ‘bite-sized yet flavourful’ story-driven add-ons, and this first chapter promises a blend of holiday chaos, explosive loot hunts, and heartwarming mischief – all set to arrive on November 20.

The story of this debut pack revolves around Rush, a fan-favorite gunslinger whose mission is to remind the Timekeeper’s Minister of Culture what Mercenary Day is truly about: generosity, camaraderie, and a healthy amount of reckless firepower.

The event promises players a festive shootout laced with signature Borderlands humor and over-the-top action.

For those diving into the DLC, Gearbox confirmed that Bounty Pack 1 introduces a new Vault Card packed with fresh rewards – including 24 unique cosmetic items and four rerollable pieces of gear. Each item offers a chance to experiment with new builds, since the reroll mechanic allows players to fine-tune their gear’s stats until they find that perfect match for their playstyle. In classic Borderlands fashion, expect hours of tinkering, testing, and triumph.

To access Bounty Pack 1, players will need either the Deluxe or Super Deluxe Edition of Borderlands 4 (both of which include the full Bounty Pack Bundle), or they can purchase the pack separately. Gearbox has clearly designed this system to give players options while rewarding those who’ve already invested in the higher-tier editions.

Alongside the paid content, Gearbox has also rolled out a free Halloween-themed mini-event titled Horrors of Kairos. Running from October 23 to November 6, this spooky event brings a haunting new twist to the Borderlands 4 world: eerie blood rain weather effects during world boss fights and a chance to score limited-time Legendary loot. Dedicated fans can also redeem exclusive seasonal cosmetics through SHiFT codes, a welcome touch for those who thrive on collecting every rare skin and charm the franchise has to offer.

Gearbox didn’t stop there. December will see the arrival of Bloomreaper the Invincible, the first in a new line of free endgame bosses. True to its name, Bloomreaper isn’t truly ‘unkillable,’ but it will push even the most seasoned Vault Hunters to their limits. Expect enormous health pools, devastating attacks, and new gameplay modifiers designed to test coordination and skill. Gearbox also revealed that this update will introduce a new Ultimate Vault Hunter Mode, raising the game’s difficulty ceiling and adding a layer of challenge that veterans have been asking for since launch.

Looking further ahead, fans can expect the arrival of the luck-based Vault Hunter C4SH in the first quarter of 2026, the first of two new characters coming via Story Pack DLC. C4SH’s ability set revolves around pure chance – meaning every encounter could either turn you into an unstoppable powerhouse or a walking disaster. It’s a bold design choice that leans into Borderlands’ unpredictable nature.

Meanwhile, the community has been busy uncovering secrets. Recent datamining hints suggest that one of the most disliked characters from Borderlands 3 was quietly scrapped during Borderlands 4’s late development stages, sparking heated debate across fan forums. Neither Gearbox nor 2K Games has commented on the discovery, leaving players to speculate whether the decision was a mercy or a missed opportunity.

Beyond the announcements, Borderlands 4 continues to foster a dedicated and passionate player base. Some fans have spent hundreds of hours farming for the perfect loot drops – one player even logged over 150 hours and 3,000 boss kills in pursuit of the game’s true drop rate. For those planning to dive in, community resources like updated SHiFT codes lists, interactive maps, and a Borderlands 4 planner tool from Maxroll remain invaluable.

As the Borderlands universe expands with Bounty Pack 1, it’s clear that Gearbox aims to blend nostalgia with fresh innovation. Whether you’re chasing loot, lore, or laughter, Mercenary Day looks to deliver all three in one chaotic, gun-slinging package.
