Arknights: Endfield Codes (October 2026)

Active Arknights: Endfield Codes (October 2026)

Last checked October 14, 2026 against the official announcements and several code trackers. Four codes work right now. Three are usable on any platform; ENDFIELD4PC is limited to PC versions.

• ENDFIELDSTEAM NEW · All platforms
  T-Creds ×8,000
  Elementary Cognitive Carrier ×2
  Arms INSP Set ×2
  Special Commemorative Portrait Frame ×1
  Expires: November 25, 2026 — 23:59 (UTC+8) on Asia servers, 10:59 (UTC-5) on Americas / Europe servers

  Released when the game passed 300,000 Steam wishlists ahead of the October 15 Steam launch. Despite the name, it is not Steam-only — mobile, PS5 and PC players can all use it.

• ENDFIELDGIFT All platforms
  Oroberyl ×150
  T-Creds ×10,000
  Intermediate Combat Record ×20
  Arms INSP Kit ×20
  Expires: no announced end date
• ZAU2SYXHWX5L4ZH All platforms
  T-Creds ×5,000
  Arms INSP Kit ×10
  Expires: no announced end date
• ENDFIELD4PC PC only
  T-Creds ×13,000
  Advanced Combat Record ×2
  Arms INSP Kit ×2
  Expires: no announced end date

  Only validates on a PC version of the game (official launcher or Epic; the new Steam release is also a PC client). Mobile and PS5 will reject it.

Codes are not case-sensitive, and each one works once per account. "No announced end date" does not mean permanent forever — the launch codes disappeared after a week, so redeem everything while it still works.

How to Redeem Arknights: Endfield Codes

A brand-new account can't redeem straight away. Clear the Process: Cold Start prologue and get free control of your character on the Dijiang first — roughly 30 minutes to an hour of play. Codes also can't be entered from the login screen; you need to be loaded into the game.

1. Open the pause menu: ESC on PC, the Options button on PS5, or the menu button on mobile.
2. Tap the cog icon in the top-left to open Settings.
3. Go to the Platform & Account tab (the person icon).
4. Find Exchange Code and press Go.
5. Paste the code and press Confirm.

Where Your Code Rewards Go

Redeemed items don't land in your inventory. They go to the in-game mailbox, which unlocks later than the Exchange Code menu — after you complete the main mission Chapter 1 Process I: Break the Siege. Once it opens, an envelope icon appears and your rewards are waiting there.

Free Oroberyl Without a Code: New Version Guide Rewards

Endfield's biggest free drops no longer come from codes. Each version, Gryphline opens a New Version Guide page on the official site with a one-time reward for every account. For the Sanctuary of Ink update it contains:

How to claim it:

1. Open the New Version Guide on the official endfield.gryphline.com site.
2. Log in with the account you play on (you must have finished character creation).
3. Press Claim Rewards. The items go to that character's in-game mail.

Reading this after October 15? This version's window has closed, but a new page opens with each Version Preview broadcast, so watch for the next one. Only use the official Gryphline domain to log in — lookalike "claim" sites are a common way accounts get stolen.

Why Your Endfield Code Isn't Working

1. Already redeemed. One use per account. Since most active codes have no end date, this is the usual reason a valid code fails — especially if you play on more than one platform.
2. Wrong platform. ENDFIELD4PC only works on PC versions.
3. Expired. Check the expired list — several codes still circulating on older lists are dead.
4. A stray space. Capitalisation doesn't matter, but a trailing space copied from a webpage will break it. Delete and paste again.
5. Prologue not cleared. If the Exchange Code option is missing entirely, this is why.
6. Rewards "missing" after a successful redeem. Your mailbox isn't unlocked yet — see where rewards go.

There is no code generator for Endfield and there never will be. Codes come only from Hypergryph / Gryphline's official channels. Any site promising unlimited free Oroberyl is either running ads or after your account details.

Expired Arknights: Endfield Codes

• AKENDFIELDSUB — 100 Oroberyl. Reported to have ended around September 9, 2026.
• ENDFIELDRENEW — 71,600 T-Creds and a Safety Helmet sticker, from the Version 1.4 livestream with an end date of August 30, 2026. A few automated trackers still list it as live; if you never used it, trying costs nothing, but don't expect it to work.
• RETURNOFALL and ALLFIELD — the launch codes from the January 16, 2026 release livestream, expired January 29, 2026. Together they gave 2,000 Oroberyl plus Combat Records, Protodisks, Protoprisms and Arms Inspectors.

Codes vs. Pulls: What Free Rewards Are Actually Worth

One Headhunting pull costs 500 Oroberyl (5,000 for a ten-pull), and 1 Origeometry converts to 75 Oroberyl. Converted into pulls, the free sources look like this:

So treat codes as a T-Creds and materials boost, not a pull budget. The free sources that actually add up are:

• New Version Guide rewards — around 1,000 Oroberyl each version, as covered above.
• Main, side and companion quests — each pays Oroberyl, and companion quests are the easiest to forget.
• Authority Level, exploration chests and events — the steady income once you're past the early chapters.

We recheck this list after every livestream and version update and move dead codes to the expired section. Last update: October 14, 2026.
