No Borderlands game launches without post-release content, and Borderlands 4 won’t be any different.

Gearbox attended PAX Australia, where Randy Pitchford combined magic tricks with new details about the post-launch roadmap for Borderlands 4. The first addition will be a Halloween-themed mini-event titled Horrors of Kairos, running from October 23 to November 6. Expect bloody rain falling during world boss fights, new legendary loot, and a pumpkin-headed cosmetic item available via Shift code.

While this update will be free, the first paid DLC, Bounty Pack: How Rush Saved Mercenary Day, is also on the way. Much like the Headhunter Packs from Borderlands 2, these smaller expansions feature a handful of missions, a boss encounter, themed cosmetics, and new legendary gear. The story focuses on Rush, the leader of the Outlanders, as he struggles to keep holiday traditions alive despite the strict cultural restrictions enforced by Screw, the Minister of Culture serving the Timekeeper. This DLC launches on November 20.

In December, a free update will add a new difficulty level to Ultimate Vault Hunter Mode and introduce an endgame raid boss reminiscent of Crawmerax the Invincible from the first game’s Secret Armory of General Knoxx DLC. The new boss, Bloomreaper the Invincible, will offer unique legendary loot drops for players skilled enough to take it down.

This wraps up the 2025 expansion roadmap. In early 2026, players can look forward to the second Bounty Pack and the first major Story Pack titled Mad Moxxi and the Vault of the Damned, which introduces a new Vault Hunter: a robot named C4sh. Additional Bounty Packs, another Story Pack, and more raid bosses are planned for later in the year. A Nintendo Switch 2 version is also rumored, though no release window has been announced.
