Arknights: Endfield Codes - Free Loot For The Grind (January 2026)

Arknights has finally ditched the tower defense grid for a real-time 3D RPG, but it definitely hasn't ditched the insatiable need for premium currency.

The franchise has moved on to base building and exploration, but the core loop remains the same: get operators, upgrade operators, run out of money. To help with the resource drought, the developers have dropped a fresh batch of codes for January 2026. These give you everything from Oroberyl to the essential T-Creds you need to keep your base running.

I have tested these myself, and I suggest you hurry. A couple of the big ones expire in literally two days, so stop procrastinating.

ACTIVE CODES (JANUARY 2026)

Get them while they are hot. The expiry dates on some of these are brutal.

RETURNOFALL	500 Oroberyl, 600 T-Creds, 30 Elementary Combat Record, 30 Arms INSP Kit, 5 Protoprism, 5 Protodisk. (Expires Jan 29)
ENDFIELDGIFT	150 Oroberyl, 10,000 T-Creds, 20 Intermediate Combat Record, 20 Arms INSP Kit.

HOW TO REDEEM CODES

It wouldn't be a modern RPG if the redemption menu wasn't hidden behind a few clicks. Before you can claim anything, you have to actually play the game for a bit. You need to complete the story mission "Valley Reboot" first. If you haven't done that, the option won't even be there.

Once you have cleared that hurdle, here is the process:

1. Open the Menu: Hit escape or tap the menu button to pause.

2. Find Settings: Click the Gear icon in the top left corner.

3. Navigate: Go to the "Platform and Account" tab.

4. Redeem: Select "Exchange Code" and type in the code exactly as shown above.

The items don't go straight to your inventory. You have to go to your in-game mailbox to collect them. If the code fails, double-check your spelling, or you might have missed the deadline. Seriously, ALLFIELD and RETURNOFALL expire on the 29th, so do not wait on those.
