For years, the Borderlands franchise has been defined by its contained, level-based zones, connected by the familiar hum of a Fast Travel station. With Borderlands 4, Gearbox has taken its most ambitious step yet, embracing a more modern, open-world structure for the new planet of Kairos.

After extensive exploration, it’s clear that this new direction has resulted in the most vibrant and activity-rich world the series has ever seen. The planet is packed with meaningful discoveries, from dynamic world bosses to rewarding dungeon-like Vaults that make exploration feel genuinely exciting.
However, this new ambition is not without its significant growing pains. While the world itself is a triumph of engaging content, its potential is often held back by a frustratingly clunky navigation system and a co-op progression model that feels strangely archaic for a game so focused on playing with friends. This is our deep dive into what it’s like to explore the massive new world of Borderlands 4.
The Structure of Kairos: A Seamless, Living World
The most significant architectural change in Borderlands 4 is the move towards a large, seamless world. While the planet of Kairos is still divided into several large, distinct zones, you can now travel between them on foot or by vehicle without being interrupted by a loading screen. This creates a much more immersive and cohesive experience, making the world feel like a real, interconnected place rather than a collection of separate levels.
The planet feels big without being bloated, and each region offers a different feel, even if the biome diversity isn’t quite as dramatic as in some past titles. What Kairos may lack in wildly different aesthetics, it more than makes up for in atmosphere. The world feels more alive than ever before, with warring factions, dynamic events, and a sense of constant activity that makes it rewarding to simply exist and explore within.
This newfound freedom of movement is magnificently supported by a huge quality-of-life upgrade: the vehicle system. The iconic Catch-A-Ride stations are completely gone. In their place, you can now instantly spawn your customizable Digi-Runner on the fly, anywhere in the open world.
This simple change is a game-changer for exploration, removing the tedious backtracking required in previous games and encouraging you to hop on your vehicle and see what’s over the next hill. It’s a modern convenience that makes getting around the massive world a joy rather than a chore.
The Thrill of Discovery: Rewarding Activities and Exploration
Where the world of Kairos truly shines is in the sheer density of meaningful content packed into its vast landscapes. Exploration in Borderlands 4 is not just about finding collectibles or ticking boxes off a map; it’s a core part of the gameplay loop that offers tangible, exciting rewards. The world is littered with side quests, challenges, and dynamic events that make veering off the beaten path feel consistently worthwhile.
Among the most exciting additions are the new Open World Bosses. These formidable enemies spawn in large, easy-to-spot energy bubbles that appear dynamically as you explore. These aren’t just scaled-up badasses; they are unique encounters that feel good to fight and, crucially, seem to always drop worthwhile loot. They provide a compelling reason to venture out into the wilderness, breaking up the travel between main quests with spontaneous, high-stakes combat.
Even more integral to the new exploration loop is the system of Silos and Safe Houses. These points of interest are scattered across each zone and must be discovered and unlocked. Once secured, they serve as valuable fast travel points, creating a convenient network for navigating the large maps. But their function goes deeper. Unlocking these locations is directly tied to a new endgame pursuit: Vault Fragment Hunts.
This system guides you on a treasure hunt across the region, culminating in the discovery of a hidden Vault. These Vaults are one of the best additions to the Borderlands formula, acting as mini-dungeons complete with unique enemies, light environmental puzzles, and a giant, mechanically interesting boss at the end. The entire loop—from finding a Safe House to hunting for fragments and finally conquering a Vault—is an incredibly satisfying and rewarding experience that makes exploration feel like a core pillar of your progression.
The Stumbling Blocks: Flaws in Navigation and Co-op
For all the brilliance of its world content, Borderlands 4 stumbles significantly in two fundamental areas: navigation and co-op progression. The new in-game navigation system, which is meant to guide you to objectives, is unfortunately a source of constant frustration. To get a waypoint, you have to perform a “scan,” which generates a visual guideline on the ground. However, this system is plagued with issues.
The scan is on a cooldown, the guideline is often faint and hard to see, it frequently disappears without warning, and it has a bizarre tendency to route you on a long, inefficient path to your destination. This forces you to rely on constantly opening your main map to navigate effectively, a workaround that is made even more annoying by the fact that the map menu itself is slow to open.
These frustrations are compounded by a baffling design choice for co-op play. In a series that has always championed its cooperative experience, world progression is not shared between players. The review provided a stark example: after completing the entire campaign and unlocking numerous activities in the host’s world, the guest player returned to their own game to find it completely untouched.
While they kept their character levels and loot, all the Silos, Safe Houses, and other open-world activities they had completed together were still locked. This forces players to repeat huge chunks of content and feels like a major step backward, discouraging the very exploration and cooperation that the rest of the game’s design so heavily promotes. It’s a significant oversight that hopefully can be addressed in a future patch.
Despite these issues, the world of Kairos is ultimately a massive success. It is the most engaging and content-rich environment the franchise has ever produced, with a rewarding exploration loop that will keep players hooked for hours on end. The foundation is incredibly strong, but its full potential is held back by the frustrating navigation and co-op systems that desperately need refinement.
