Borderlands 4 Reveals Bounty Pack 1: How Rush Saved Mercenary Day, the First Seasonal Mini-Event, an Invincible Boss, and More

Gearbox has revealed Borderlands 4 Bounty Pack 1: How Rush Saved Mercenary Day, the first seasonal mini-event for the game, an invincible boss, and more.

Bounty Packs are paid DLC that bring new “bite-sized-yet-flavourful” narrative content to Borderlands 4. In Bounty Pack 1, due out November 20, players team up with Rush and “show the Timekeeper's Minister of Culture the true meaning of Mercenary Day, a jolly time for gift-giving and gunslinging with friends and family.”

Bounty Pack 1 also includes a Vault Card with new rewards that players will earn through gameplay, with 24 cosmetic items to unlock and four pieces of rerollable gear. The rerollable gear can be earned as many times as players like, so it can be an opportunity to obtain a roll with stats that perfectly suit a specific build, Gearbox said.

Here’s the official blurb:

Rush, the affable leader of the Outbounders, is feeling homesick and nostalgic for the holidays he's cherished in years past. By his calculations, it's about to be Mercenary Day, a jolly time for gift-giving and gunslinging with friends and family, and he'd like to bring that same festive cheer to the people of Kairos. But his hopes for holiday merriment stand in direct opposition to Screw, the Timekeeper's Minister of Culture who's charged with keeping celebrations as bland and homogenous as possible. Across a series of all-new Main Missions, you'll show Screw the true meaning of Mercenary Day by any means necessary, and maybe score some new Legendary loot in the process.

Here's the full breakdown of the Borderlands 4 Bounty Pack 1 Vault Card loot:

• 4 rerollable weapons
• 4 Vault Hunter Heads usable by Vex, Rafa, Amon, and Harlowe
• 4 Vault Hunter Skins usable by Vex, Rafa, Amon, and Harlowe
• 5 Weapon Skins
• 5 Vehicle Skins
• 4 ECHO-4 Drone Skins
• 2 ECHO-4 Attachments

Bounty Pack 1 also features a few extras to find:

• 1 New Digirunner Vehicle (available shortly after starting the first Main Mission)
• 1 Vault Hunter Style usable by Vex, Rafa, Amon, and Harlowe (available after beating the boss and completing the Bounty Pack's final Main Mission)
• 1 ECHO-4 Drone Skin (available after beating the boss and completing the Bounty Pack's final Main Mission)

To access Gearbox has revealed Borderlands 4 Bounty Pack 1: How Rush Saved Mercenary Day, the first seasonal mini-event for the game, an invincible boss, and more., you need to have either bought the Borderlands 4 Deluxe or Super Deluxe Edition (both include the Bounty Pack Bundle), or bought the Bounty Pack Bundle that includes Bounty Pack 1, or bought Bounty Pack 1 individually.

Meanwhile, Gearbox revealed Borderlands 4’s free seasonal mini-event, Horrors of Kairos. This limited-time event celebrates Halloween from October 23 to November 6. Players will encounter a terrifying new weather effect of blood rain when fighting world bosses, and killing them has a chance to earn you new Legendary loot, Gearbox said. Seasonal cosmetics will be offered through SHiFT codes, too.

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

And finally, there’s a free endgame update in the form of Bloomreaper the Invincible. This is the first of the endgame Invincible Bosses coming to Borderlands 4 as free DLC, and is due at some point in December.

The "Invincible" moniker is a throwback to the raid bosses of Borderlands 2, so these aren't literally unkillable enemies, Gearbox explained, but players' skills “will be tested by the massive health pools, extremely lethal attack damage, and new modifiers of these all-new bosses.”

The December update also adds a new Ultimate Vault Hunter Mode level for an added layer of difficulty.

Last month, Gearbox revealed Borderlands 4’s first of two new Vault Hunters coming to the game as part of the paid Story Pack DLCs. C4SH, due out during the first quarter of 2026, is a playable character whose luck-based powers can make him either the best or worst character in the game.

We’ve got plenty more on Borderlands 4. Last month, a Borderlands 4 dataminer unearthed evidence to suggest that one of the most hated characters from Borderlands 3 was cut and replaced relatively late in development. 2K Games and Gearbox declined to comment when contacted by IGN.

And we recently interviewed a Borderlands 4 player who spent 150 hours on over 3,000 boss kills to find out the game’s true drop rate.

If you are delving into Borderlands 4, don't go without updated hourly SHiFT codes list. We've also got a huge interactive map ready to go and a badass Borderlands 4 planner tool courtesy of our buds at Maxroll. Plus check out our expert players' choices for which character to choose (no one agreed).
