Arknights: Endfield Codes — October 2026

Exchange codes with exact reward amounts, plus the AIC blueprint import codes we could verify and the ones we pulled.
Last checked October 24, 2026Editorial refresh August 13, 2026Arknights: EndfieldCode Guide
October 24, 2026 recheck: The official endfield.gryphline.com news post of October 6, 2026 adds ENDFIELDSTEAM — 8,000 T-Creds, redeemable October 6 to November 25, 2026 — landing with the "Sanctuary of Ink" version update of October 6, 2026, while BlueStacks (October 1, 2026) still lists ENDFIELDRENEW as new despite its published August 30 deadline, so that row moves to caution, and BlueStacks files the two launch codes spent.
Trust note: Re-checked September 20, 2026 and no row needed changing — the freshest dated code lists we could confirm this pass are GamesRadar (September 3, 2026) and Game8 (September 4, 2026), and neither carries an exchange code that clears our two-source bar or a blueprint string that clears it either, while a version 1.5 preview circulated on August 24, 2026 through third-party reporting only, which we label as such and whose contents we are neither describing nor listing. ENDFIELDRENEW's published deadline of August 30, 2026 is the only clock on this page — that published window has now elapsed on the calendar, so treat that row as due for an in-game check; we have left the table alone rather than move a row on a date.

Context for anyone arriving cold: Endfield has two unrelated things called "codes". Exchange codes are reward codes typed into the account menu. AIC blueprint codes are long strings that import a factory layout and carry no reward at all. On August 13 we cut a large blueprint table that had been credited to a source which does not publish blueprint codes; it stays cut, and we did not go looking for a reason to restore it.

Exchange Codes (Reward Codes)

These are the codes that pay out. Endfield's currencies are Oroberyl (premium) and T-Creds, with Combat Records and Arms INSP Kits as materials. Every row below is carried by at least two independent trackers agreeing on the exact string and reward.

One further code was reported at our August 16 read: a WhatsApp/Messenger promotion worth 100 Oroberyl with a September 9, 2026 deadline. We are not printing a string for it, because no source we checked published one we could corroborate.

AIC Blueprint Codes — What We Could Verify

⚠️ Important: Blueprint codes are region-locked — NA/EU codes won't work on Asia servers and vice versa. They are also case-sensitive, and capital I, lowercase l and the digit 1 are easy to confuse when retyping by hand. Copy, never retype. Read our disclaimer.

Blueprint sharing is a real in-game feature and these codes give no rewards — they rebuild a factory layout. The problem is verification: the strings are twenty-odd characters of mixed-case filler, they are patch-specific and region-specific, and almost no outlet republishes the same string as another. Below are the only entries we could match against an independent published list.

What We Removed and Why

Around twenty further blueprint strings previously sat on this page across four tables, credited to Pocket Tactics. On re-checking, Pocket Tactics publishes Endfield exchange codes and no blueprint codes whatsoever, so that credit was wrong and the strings had no stated origin. Two further problems showed up on inspection:

  • An "Infinite Seed-Planter Loop" row and a "Sandleaf Infinite" row carried the identical Asia string, with the second row's other column left as a bare dash where a value should have been. They were one blueprint listed twice, not two blueprints.
  • A "Ferrium Component" string differed from the seed-planter string by a single inserted character. One of the two was a corrupted copy of the other, and there was no way to tell which.

We have removed the uncorroborated rows rather than leave them sitting under a citation that does not support them. A blueprint code that is one character wrong simply fails to import, so a bad list here costs time rather than money — but it is still a list we cannot stand behind.

Sources checked October 24, 2026: the official endfield.gryphline.com news (October 6, 2026 post — ENDFIELDSTEAM with its redeem window, and the Sanctuary of Ink update) and BlueStacks (October 1, 2026, cited by name — files the launch codes spent and still lists ENDFIELDRENEW), then the reads from the previous check: Game8 redeem codes (its own page stated August 10, 2026); Pocket Tactics (its own page stated August 10, 2026); Beebom (its own page stated updated August 1, 2026); Game8's banner schedule (its own page stated August 9, 2026) for the version 1.5 position; AllThings.how NA/EU blueprint list (its own page stated January 27, 2026) and its wider blueprint list (its own page stated March 17, 2026); Game8 blueprints page (its own page stated August 11, 2026, but serves its codes through copy buttons rather than printed text). None of the code trackers had refreshed between our August 13 and August 16 checks. GGGuides labels these as dated signals unless confirmed in-game.

How to Import Blueprints

  1. Teleport to a core AIC area or Outpost
  2. Enter AIC Mode → switch to Top View (Q on PC)
  3. Press F1 to open the Blueprint menu
  4. Go to Shared Blueprints tab → Import
  5. Paste the code exactly (case-sensitive)
  6. Confirm to place the blueprint in your base
Tip: If an import is rejected, the usual cause is a character swap between capital I, lowercase l and the digit 1, or a code built for the other region. Neither failure gives a useful error message, so re-copy first and only then suspect the region.

What to Verify Next

ENDFIELDRENEW has a published deadline of August 30, 2026, and ENDFIELDSTEAM carries a first-party window to November 25, 2026 — the two rows on this page with clocks on them. Blueprint codes are tied to a game version — codes written for an earlier patch may import into a layout that no longer matches current recipes, which is a separate failure from a code being wrong.

The next realistic code event is the version 1.5 livestream, since ENDFIELDRENEW itself came from the 1.4 broadcast. Gryphline had not announced a 1.5 date at our August 16 check, and the outlets guessing at one do not agree with each other, so we are not printing a date. The nearest thing to a real signal at that same August 16 read was the Liino banner, which Game8 published as running to September 2, 2026 — versions begin when banners turn over, so that was the window to watch rather than any leak roundup.

Gryphline's other August news — a Steam version and Gamescom booths on August 26 to 30 — are announcements, not code drops. Convention appearances for this game have not produced exchange codes before, and we will not list one on the strength of a booth being present.

Update Rule

We do not mark a code as active just because another page says it is active. The page records what was checked, when it was checked, and what players should verify next.
