Borderlands 4's first major story DLC has arrived, and it's shaping up to be the biggest content drop the game has seen since launch. Story Pack 1: Mad Ellie and the Vault of the Damned brings a brand-new zone, a fresh playable Vault Hunter, two major boss fights, 16 minibosses, and a pile of Legendary and Pearlescent loot to chase. Whether you're a returning fan or jumping in for the first time, this guide breaks down everything worth knowing before you set foot on the frozen wastes of The Whispering Glacier.
What Is Borderlands 4 Story Pack 1?
Mad Ellie and the Vault of the Damned is a self-contained story expansion for Borderlands 4, developed by Gearbox Software and published by 2K. It launched on March 26, 2026, and is included with the Vault Hunter Pack and the Super Deluxe Edition, though it can also be purchased separately.
The story follows Vault Hunters teaming up with Ellie, mechanic extraordinaire and daughter of Moxxi, to destroy an alien monolith and breach the cursed Vault of the Damned. Guiding your journey is the returning fan-favorite Mancubus Bloodtooth, alongside oddballs like Pickle and Crazy Earl.
info
This DLC is designed to be fully self-contained. You don't need prior knowledge of Borderlands 4's main story to enjoy it, making it accessible to players of any experience level.To access The Whispering Glacier, you need to own Story Pack 1 and complete the "A Lot to Process" mission in the Fadefields. The content is recommended for Vault Hunters at level 13 or higher, and you can also start a brand-new character that skips directly into the DLC at level 13.
How Do You Unlock The Whispering Glacier?
Getting into the new zone requires a couple of straightforward steps:
- Own Story Pack 1: Mad Ellie and the Vault of the Damned.
- Complete the "A Lot to Process" mission inside the Fadefields region.
- Bring your Vault Hunter to level 13 or above (or create a new character that starts at level 13 directly in the DLC).
Once inside, you'll find a frozen expanse filled with derelict ship husks, dark secrets, and plenty of hostile factions to tear through.
info
If you want to jump straight into the DLC story without replaying the main campaign, use the new character skip option to start at level 13 directly in the Mad Ellie content.
Who Is C4SH the Rogue?
C4SH is a CasinoBot and the first of two new DLC Vault Hunters coming to Borderlands 4. His backstory is genuinely one of the more creative character concepts in the franchise: after winning a high-stakes card game, he acquired a magical deck that grants him eldritch boons. For a robot who has spent his existence calculating odds across the solar system's casinos, the sudden experience of true unpredictability makes him feel, for the first time, human.
That philosophy drives his entire playstyle. C4SH is built around high-risk, high-reward gambling mechanics, bending luck in your favor to dismantle enemies fast.

What Are C4SH's Action Skills?
C4SH comes equipped with three unique Action Skills and three branching skill trees packed with Passives and Augments. His signature skill, Sleight of Hand, lets him draw cards from a randomized deck and throw them to unleash powerful spells. The randomized nature of the deck keeps combat unpredictable and rewards players who adapt on the fly.
Full details on all three Action Skills will be revealed closer to the DLC's release, so expect more depth once the official gameplay reveal drops.

C4SH's full gameplay reveal and cinematic character short are scheduled for the week before Story Pack 1 launches. Keep an eye on official Gearbox channels for the complete skill breakdown.
What Enemies and Bosses Are in Story Pack 1?
The Whispering Glacier is not a friendly place. You'll face several distinct enemy factions and a serious roster of threats:
- DAHL Legion soldiers: Grizzled troops who abandoned their posts on Elpis and now terrorize Kairos.
- Kraggons: Returning creature enemies known for their aggression.
- Scavs: Classic Borderlands bandits making their presence felt on the glacier.
Boss Breakdown
The standout new mechanic is the World Boss system: when players interact with specific eldritch trees in the zone, they're transported to a nightmarish dimension where a random boss awaits. This adds genuine replayability to the endgame loop, since you never know exactly what you're walking into.
Later in mission progression, you can also destroy massive growths of pulsating flesh to unlock new areas, additional loot, and environmental puzzles.

What Free Updates Come With Story Pack 1?
Alongside the paid DLC content, Gearbox is releasing a major free update for all Borderlands 4 players. The headline feature is shared progression across characters: new characters on the same account will inherit map progression, SDU tokens, Hover Drives, cosmetic rewards, and activity progression.
warning
Some fast-travel locations will still be locked behind campaign progression in new playthroughs, even with shared progression active. Plan your route accordingly when starting a fresh character.
This is one of the most requested quality-of-life features since launch, and it arrives at no extra cost.
What's Coming After Story Pack 1?
Gearbox has a clear post-launch roadmap in place. Here's what's confirmed beyond the first story pack:
- Raid 2 and a new Takedown (free for all players), building on the existing Bloomreaper the Invincible raid boss.
- Bounty Packs 3, 4, and 5 releasing throughout Q2 and Q3 2026, each featuring a Vault Card with new cosmetics, gear, and narrative mission content.
- Story Pack 2 arriving in Q3 2026, introducing another brand-new Vault Hunter, multiple main and side missions in a new zone of Kairos, fresh gear, and additional cosmetics.
The roadmap makes it clear that Borderlands 4 has a full year of content ahead, with Story Pack 1 being just the opening act.
Is Story Pack 1 Worth It?
Based on the confirmed content, Story Pack 1 packs a serious amount of value into a single DLC:
- A brand-new playable Vault Hunter with a unique randomized-deck mechanic
- A full new zone with main missions, side quests, and collectibles
- 18 total boss encounters (two major, 16 minibosses)
- 14 new pieces of high-rarity gear (three Pearlescent, 11 Legendary)
- 28 cosmetic items
- A free major update with shared character progression
For players who own the Super Deluxe Edition or Vault Hunter Pack, this is already included at no additional cost. For everyone else, the sheer density of new content makes it a strong pickup, especially if you're invested in building out C4SH or hunting those three new Pearlescent weapons.
