March has been a hot month on Talos II. You’ve just established your supply chain, but your resources are running low again, and the desired spinning is a long way off. Sound familiar? Don’t be too upset or reach for your wallet. There’s a way to replenish your supplies faster than your assembly line can produce parts. We’re talking about special Arknights Endfield promo codes , which are still working.
We’ve checked the current Arknights Endfield promo codes for March 2026, weeded out any expired ones, and are ready to tell you not only what you can get right now but also detail where to enter these coveted codes to ensure your rewards arrive in your inbox. In this article, you’ll find all the working codes, understand how to activate them on various platforms, and discover which 2026 promo codes have already been consigned to the archives.
New Arknights Endfield promo codes for March 2026
Of the four starting codes given to players at launch, only two remained active by March 2026. The good news is that they’re still active and generously sharing resources. The bad news is that the developers haven’t yet released any new promo codes for the upcoming 1.1 update, which drops on March 12. But it’s only a matter of time. Here’s a list of what’s available for activation right now:
- ENDFIELDGIFT. This versatile set is a must-have for any End Administrator. It includes 150 units of the premium Oroberil currency, 10,000 T-Credits for everyday needs, 20 intermediate combat records for squad leveling, and 20 test kits for weapon upgrades. A great help at the start or midway through your journey.
- ENDFIELD4PC. There’s a catch: as the name suggests, this code is platform-locked. It can only be activated on the PC version of the game. The reward is 13,000 T-Credits, a couple of Advanced Battle Records, and two Weapon Test Kits. If you’re playing on PC, this is a free bonus. Mobile device owners, unfortunately, will have to settle for the first option.
All ArcNights Endfield promo codes, unlike many other games, are case-insensitive. This means you can enter them in uppercase or lowercase – they’ll work just as well. However, we recommend not delaying activation: no one knows when they’ll stop working.
How and where to enter Arknights Endfield promo codes
Let’s say you’ve found the coveted set of symbols. The obvious question is: where do you enter this magic phrase? Arknights Endfield doesn’t have a separate website for activation—everything is done directly in the game. But there’s a catch: the input field doesn’t appear immediately, only after completing a short prologue.
Here’s a step-by-step guide on how to get to the coveted button and receive prizes:
- Start the game. You’ll need to complete the very first mission, called “Process: Cold Start.” Once you’re on the Dijiang ship and gain control of your character, the game will unlock the settings menu;
- Open the menu. Press the Esc key (on PC) or look for the gear icon in the upper left corner of the screen on the main console;
- In the Settings menu, go to the “Platform & Account” section. Scroll down the list of options until you see “Exchange Code.” Click the “Go” button next to it.
- Enter the code. A small text field will appear. Feel free to enter new promo codes from the list above and click the confirm button;
- Claim your reward from your mailbox. This is the most important part. Once activated, the reward does NOT appear in your inventory immediately. It arrives in your in-game mailbox. However, your mailbox opens a little later, after completing one or two more story missions. As soon as the envelope icon appears on the screen, go ahead and claim everything you’ve received.
As you can see, the process is simple. The main thing is to remember to play a little first before entering the codes. And one more tip: if you’re playing on PC, activate both available promo codes—they complement each other perfectly.
Expired Arknights Endfield promo codes
As mentioned earlier, the initial bonuses proved short-lived. Two very generous codes that offered tons of resources at launch stopped working at the end of January. If you come across these codes anywhere online, don’t even try to enter them—they’re no longer valid.
Here’s a list of things that won’t work anymore:
- RETURNOFALL. This set was a true godsend. It contained 500 Oroberyl, 6,000 T-Credits, 30 Elemental Battle Records, as well as Protodiscs and Protoprism crafting trophies. Expired January 29th.
- ALLFIELD. The fattest code of them all. It gave 1500 Oroberyl! With such a supply, you could afford a few extra spins in hopes of landing a cool character. It also came with credits, notes, and a special item, “Badge of Fortitude.” Unfortunately, it also disappeared on January 29th.
Most likely, the remaining active ArcKnights Endfield promo codes will also eventually stop working. This usually happens either a month after the game’s launch or after major patches. With version 1.1 just around the corner, it’s best to activate your remaining bonuses as soon as possible. Who knows, perhaps the developers will release a fresh batch of new promo codes with the March 12th update and cancel the old ones.
