Sirens are one of the most iconic classes in all of Borderlands, with supernatural Phase abilities that augment their run-and-gun expertise. It's high time we formally introduced you to Vex the Siren, one of the four all-new Vault Hunters who are wreaking havoc on Kairos in Borderlands 4!

In the Vex Gameplay Overview above, you can witness Vex's destructive Phase energy in action, whether she's blasting enemies to bits with elemental orbs, summoning an entourage of aggressive Phase Clones, or letting her adorable (and deadly) feline Phase Phamiliar, aptly named Trouble, tear the opposition limb from limb. If you're generally a fan of companion classes or like to rack up kills with elemental damage, Vex is a great choice.

Here's a high-level overview of the core Action Skill abilities Vex has at her disposal:

• Dead Ringer: Use multiple charges to spawn in a posse of Phase Clone Minions, which can be melee-slashing, enemy-taunting Reapers or immobile, turret-style Specters. These Minions aren't long for this world as they continually lose health the moment they spawn in, so enjoy their murderous tendencies while they last.

• Incarnate: Unleash devastating area-of-effect damage with Incarnate's initial Phase Explosion, decimating nearby aggressors and fully healing Vex in the process. She then enters a temporary powered-up state (peep that skeletal wingspan) which has faster movement and the ability to fire off blistering Eldritch Blasts.

• Phase Phamiliar: Invite Trouble to show off what a good boy he is, particularly when it comes to chomping down on enemies or fatally smacking them to bits with his tail. When it's time to take out a high-priority target, Trouble can teleport on top of them with an instantly damaging blast before taking on an even more Badass form.

Every Vault Hunter has access to three unique Action Skills, but only one can be equipped at a time. They also have three distinct skill trees, each stemming from an Action Skill.
By investing points into a skill tree and unlocking its deeper layers, you'll gain access to Augments that provide secondary bonuses to your Action Skills, and Capstones which modify or override specific Action Skill functionalities. Augments and Capstones can only be slotted into the Action Skill for that respective skill tree. Only one Capstone can be equipped at a time, and the same is typically true for Augments.

You can use Action Skills from other skill trees even if you haven't invested any points into them, but you won't be able to equip the powerful Augments or Capstones from one skill tree onto the Action Skill of a different skill tree. Committing Skill Points to the skill tree that will properly synergize with your favorite Action Skill is key!

Each Vault Hunter also has their own Trait: an always-on passive effect that doesn't require any skill points. Vex's Trait is Phase Covenant, which attunes her Action Skill and melee damage to the same Elemental Type as the gun she's currently wielding. Elemental damage types are critical for taking down tougher enemies on higher difficulty levels, so Phase Covenant is a gift that keeps on giving while you level up, incentivizing you to curate a loadout with differing elemental damage guns that ensure you're ready for anything.

Above, you can watch Vex's new Character Short "Purple Friday," featuring Vex's retelling of the events that set her down the path to becoming a Vault Hunter.

We'll also be rolling out dedicated Vault Hunter pages for the remaining crew members Rafa, Amon, and Harlowe, each with their own Gameplay Overview and Character Short, so stay tuned for those!

Borderlands 4 is an all-new adventure in the iconic looter shooter series, with a fresh story set on the unfamiliar planet Kairos that serves as a perfect entry point for new players. As you might've seen in the recent Borderlands 4[borderlands.2k.com] Story Trailer[borderlands.2k.com], Kairos and its people are being dominated by the oppressive Timekeeper—but four badass Vault Hunters are about to break free from his control and violently disrupt his perfect Order.

For the latest installment of our Beyond the Borderlands series featuring behind-the-scenes insights from the team at Gearbox, you can hear more about Borderlands 4's overarching story from Managing Director of Narrative Lin Joyce and Narrative Director Sam Winkler. They discuss the current state of unrest on Kairos, how the Timekeeper stands out from the main villains of previous Borderlands games, and the factions you'll need to recruit on your mission to take down the Timekeeper and his region-ruling Commanders. 

In addition to the info in the Beyond the Borderlands #2 video above, we asked Sam for more intel on the Crimson Resistance, an upstart faction on Kairos led by the intergalatically infamous Claptrap, and the unhinged Rippers who are loyal to Callis the Ripper Queen:

Narrative Director Sam Winkler: The Crimson Raiders have split up to search the galaxies for where Elpis and Lilith ended up. Claptrap was aboard Sanctuary III with one of those search teams when they found Kairos and crashed down, scattering the crew across the world. Claptrap attempted to "tuck and roll" out of the hangar bay door, but instead invented a new technique known as "bounce and scream." Ever resourceful and desperate to be the center of attention, the lonely robot founded a new splinter group known as the Crimson Resistance to give the residents of Kairos the same kind of hope that led to Pandora being freed of its own tyrants.

Yes, along with crippling depression and so much ECHOnet spam mail that he is legally classified as malware.

The Vault Hunters' fight against the Timekeeper is personal: they want their freedom, and they want what's in the Vault he is protecting. But Kairos is teeming with different groups who yearn to be free. The Crimson Resistance will only become a threat to the Timekeeper if the Vault Hunters can band all those different groups together into an open rebellion against his rule. Each group—the Outbounders, the Augers, and the Electi—are dealing with threats of their own, and it's up to the Vault Hunters to take down the bosses in each zone to earn trust from the people of Kairos.

Rippers are formerly Bolted Kairosians who survived the violent process of ripping out their own Bolt. Callis, once the Timekeeper's greatest military leader, was the first Ripper. In the wake of the Cataclysm—when Elpis tore open the sky and brought chaos to a closed system—Callis saw a vision of herself in the flames. She was free of the Timekeeper's control. And in that moment, she knew what had to be done. Many loyal soldiers followed in line. And those that didn't were ripped by force.

Callis is leading her people to freedom—her vision of freedom, specifically. She saw a whole universe through the hole in the veil above Kairos, and she wants to lead her armies upward, conquering all of it. The Timekeeper must keep Kairos secret and protected, and so he must stop her at any cost.

Callis has always been drawn to power. She has replaced any part of her body she deems too weak to survive—and added on even more. But if you mean logistically, I have to imagine there was some sort of elaborate harness and pulley system to get them installed.

Borderlands 4 is now available for pre-purchase! While you wait for the game's launch on September 12, 2025, keep your eyes peeled for more Beyond the Borderlands videos that detail the making of Borderlands 4!
