Arknights: Endfield offers a code redemption feature for players to obtain various in-game items. Redemption codes are usually shared through official events, social media, or specific campaigns. Players can redeem these codes directly through the in-game menu with fairly simple steps. Here's a list of the codes:

• ALLFIELD: 1 Mask of Preseverance, 5 Protodisks, 5 Protoprisms, 30 Arms Inspectors, 30 Elementary Combat Records, 1,500 Oroberyl, and 6,000 T-Creds.
• ENDFIELD4PC: 2 Advanced Combat Records, 2 Arms INSP Kits, and 13,000 T-Creds.
• RETURNOFALL: 5 Protodisks, 5 Protoprisms, 30 Arms Inspectors, 30 Elementary Combat Records, 500 Oroberyl, and 6,000 T-Creds.

Before redeeming, ensure your Arknights: Endfield account is linked to an official account and the game has been updated to the latest version. A stable internet connection is also required for the code redemption process to run smoothly. Please note that this code is only valid until January 29, 2026.

First, open Arknights: Endfield and log in to the account you wish to use. Once in the main menu, look for the Settings icon, usually marked with a gear symbol. This menu can be accessed directly from the main screen without having to enter a specific game mode.

In the Settings menu, select the Account tab. Here, players will find the Redeem Code option. Tap it to open the code input field. Enter the redeem code correctly, including capital letters, lowercase letters, and numbers in the original format.

After entering the code, press the Confirm or Redeem button. If the code is still active and has not been used before, the system will display a notification confirming the successful redemption. The reward will be sent directly to your in-game mailbox and can be claimed at any time.

If a code cannot be used, it's usually due to several factors, such as the code having expired, having already been used, or entering the wrong characters. Make sure there are no extra spaces when copying the code, as this can cause the redemption to fail.

Please note: each account can only use one code once. The rewards received may vary depending on the type of code used, ranging from in-game currency to early progress support items. By following these steps, players can redeem Arknights: Endfield codes quickly and safely.
