Don’t sleep on these Arknights: Endfield launch codes — they expire in 7 days

If you’re planning to jump into Arknights: Endfield when it launches January 22, 2026, you’ve got a tight one-week window to grab free launch resources. Hypergryph has put three redemption codes live, and every one expires on January 29, 2026.

All three codes are active from launch day through January 29. One code, ENDFIELD4PC, only works on PC. The other two, ALLFIELD and RETURNOFALL, work on all platforms.

To redeem, open the game, finish the tutorial, go to Settings or Account, choose Redeem Code, and type the code exactly as written. Codes are case-sensitive and can only be used once per account.

Separately, pre-registration rewards — including the Snowshine 5-star Operator, Finishing Call 5-star weapon, 20 Advanced Combat Records, 20 Basic HH Permits, and 30,000 T-Creds — will arrive via in-game mail after servers go live.
