Unlock Borderlands 4 Power: Try These Active SHiFT Codes ASAP

These are the latest SHiFT codes that unlock epic loot and cosmetics in Borderlands 4, but you must act quickly.

The biggest looter shooter of the year, Borderlands 4, is out, and players are already taking the fight to the Timekeeper on Kairos. If you want to put the beat down on someone strong enough to control time, then you’re going to need an arsenal of powerful weapons and equipment.

Luckily, developer Gearbox Software is willing to lend a helping hand. Instead of having to farm every piece of legendary equipment in-game, you can roll the dice on some loot with Golden Keys unlocked by SHiFT promo codes.

If you’re already swimming in more loot than you know what to do with, some SHiFT codes also unlock special cosmetic looks for your favorite vault hunters. Special in-game challenges have already unlocked promo codes for Amon, Rafa and Vex vault hunter skins, with a Harlowe skin unlocking soon. Here’s how to use the latest SHiFT codes in Borderlands 4.

All active SHiFT codes for Borderlands 4

You can hunt down SHiFT codes on social media, but we’ll keep all of the active promo codes in one place for ease of access.

Below, you’ll find a chart that contains every active SHiFT code for Borderlands 4, what it unlocks and its expiration date:

How to redeem SHiFT codes for your Borderlands 4 account

While SHiFT codes are totally free rewards for you to accumulate, you must make a SHiFT account to input any active codes in-game.

SHiFT is a service that Gearbox integrates into its biggest games, and making an account unlocks forums and exclusive beta participation. It’s also necessary to create an account to turn in any promo codes, which is what most fans care about.

Once your account is created, you can enter your SHiFT codes in two separate places. Within your SHiFT account settings, you can find a Rewards tab with a field to enter any Borderlands promo codes. Once you enter the codes, any unlocked items will be added to your account the next time you open the game.

However, an easier way to input your SHiFT codes is within Borderlands 4 itself. Within the game’s pause menu, you can access a SHiFT. Select the Rewards tab from the resulting menu, input your codes and the unlocked items will be immediately available on your save.

Where are SHiFT codes normally released?

SHiFT codes are released frequently on Gearbox and Gearbox-affiliated social media channels. For the best chance at catching every new SHiFT code that gets released, you should follow Gearbox on X and on Facebook.

Gearbox CEO Randy Pitchford also releases promos on his X account, so if you’re brave enough to follow him despite his frequent outbursts toward fans you can find SHiFT codes there as well.

What are SHiFT codes?

SHiFT codes are promo codes that Gearbox occasionally releases that reward players with loot and cosmetics in Borderlands games. The main SHiFT code reward is a Golden Key, which opens the Golden Chest in most Borderlands hub areas.

But don’t spend them immediately — it’s worth saving your Golden Keys until you reach the level cap and are playing on the hardest difficulty, as the loot rewards will scale to your character accordingly. This is a great way to begin farming some endgame legendaries quickly and easily.

Yes, This Swimming RoboTurtle Is Adorable. It Also Has an Important Environmental Mission

Beatbot is best known for making pool-cleaning robots, but it was its swimming robot turtle that won our hearts at CES 2026.

Few things in life have made me feel more privileged and awestruck than the opportunity to swim with sea turtles in their natural environment. The way in which these gentle creatures navigate through their underwater world with their deliberate and careful fin strokes is utterly mesmerizing to watch.

It’s a distinctive style of movement — so much so that when I saw Beatbot’s RoboTurtle swim across a water tank on the show floor at CES 2026, I knew that this wasn’t simply just a pool cleaner robot with turtle features tacked on. This was a studied example of biomimicry in action.

The reason for this is that the company’s engineers went on a two-month expedition to study sea turtles in their natural environment, Beatbot’s Eduardo Campo told me as we watched Turtini (the team’s affectionate nickname for RoboTurtle) splash around in its pool. «We did a lot of motion capture, like the things they use in movies, because we need to develop those joints that it has,» he said.

This isn’t RoboTurtle’s first time at CES — it also appeared in 2025 as a static concept. This is the year, however, it’s found its fins, so to speak. Not only can it swim, but it can also respond to hand gestures: I throw it an OK gesture, and it dances in response. But as cute and limber as it is, RoboTurtle is a robot with an important mission.

RoboTurtle is an environmental research tool, built with input from researchers and NGOs, which can go where humans or other machines cannot for fear of disturbing complex and delicate underwater ecosystems, particularly coral reefs. It can move silently and naturally in a way that won’t scare wildlife, monitoring water quality and fish numbers with its built-in camera.

«One of the groups that we’re working with, they want to study the coral reefs in near Indonesia,» said Campo. «There was a very big incident over there with a boat that came up onto a coral reef and it disrupted the environment, [so] they want the least intrusive robot possible.»

The group wants to deploy RoboTurtle for certain periods every year to monitor the recovery of the coral and monitor the fish population, he added. Beatbot is currently training the built-in AI to give RoboTurtle monitoring and recognition skills.

At CES, I watched RoboTurtle paddle about only on the surface of the pool, but it can also dive down up to five meters. However, it needs to resurface to send data and its GPS signal back to base, much like a real turtle that needs to come to the surface to breathe. This also gives it a chance to recharge via the solar panel on its back.

Even though I was impressed with RoboTurtle’s swimming ability, Campo estimates that the Beatbot team is still a year and a half away from perfecting its technique, with the robot ready for full deployment in between three to five years.

CES 2026 is a show where tech with a real purpose feels scarce, so it sure is refreshing to see a company use its expertise to build something designed with a sustainable future in mind. It might be a while until we see RoboTurtle take to the seas, but I’m glad that I got to witness it at this stage of its journey.

These Tiny Robots Are Smaller Than Grains of Salt and Can Think, Move and Swim

Despite their size, the robots can navigate liquids, respond to their environment and operate without external control.

Robots smaller than a grain of salt? It sounds like science fiction, but researchers have developed autonomous microrobots that can move through liquids, sense their environment and operate independently using only light as a power source.

The microrobots, developed by researchers at the University of Pennsylvania and the University of Michigan, measure roughly 200 by 300 by 50 micrometers. Yet they can detect temperature changes, follow programmed paths and function independently for months at a time.

Their work was reported this week in two scientific journals, Science Robotics and Proceedings of the National Academy of Sciences.

«We’ve made autonomous robots 10,000 times smaller,» senior author Marc Miskin, assistant professor in electrical and systems engineering at Penn Engineering, said in a statement. «That opens up an entirely new scale for programmable robots.»

Powered entirely by light, the robots don’t move using mechanical limbs. Instead, they generate tiny electrical fields that push ions (electrically charged particles) in fluid to create motion, an approach better suited to the unique physics of the microscopic world, where traditional motors don’t work.

Unlike earlier microrobots, these devices combine sensing, computing, decision-making and movement in a single, self-contained system at an extremely small scale.

Previous efforts in microrobotics have often relied on external controls, such as magnetic fields or physical tethers, to guide movement. These new microrobots, however, incorporate their own miniature solar cell-powered processors, allowing them to respond to their environment, communicate through patterned movements visible under a microscope and carry out tasks without outside direction.

Potential applications include monitoring biological processes at the cellular level, supporting medical diagnostics or helping assemble tiny devices. Because each robot can be mass-produced at very low cost, the technology opens new avenues for research and engineering at scales that were previously unreachable.
