Arknights remains one of the most demanding tower defense games on mobile in 2026. Its maps punish careless deployment, and enemies often overwhelm unprepared squads. That difficulty is exactly why redemption codes matter. They provide free resources that can ease early progression or help veterans stock up for limited events. This guide compiles active codes, expired codes, and a simple redemption process. It is based on the official redemption page and community tracking.

Why Arknights Codes Are Worth Redeeming

Codes in Arknights usually grant Furniture Parts, Strategic Battle Records, LMD, and Orundum. Each reward serves a different purpose. Furniture Parts let players decorate the dormitory. Strategic Battle Records provide operator experience. LMD is the primary currency for upgrades and promotions. Orundum is used for headhunting and stamina refills. For new players, these rewards can accelerate squad building. For veterans, they supplement event farming. The developers, Hypergryph, release codes through livestreams, social media, and special collaborations. Most codes expire quickly, so redemption should be a habit.

Active Codes

The table below lists codes that were reported active in early 2026. ⚠️ Codes are case-sensitive and can expire without notice. Redeem them as soon as possible.

Players should note that some codes are region-specific. A code that works on the global server may fail on the Japanese or Korean server. The official redemption page automatically detects the server after the UID is entered. If a code does not work, it may have reached its redemption limit or expired.

How to Redeem Codes in Arknights

The redemption process is straightforward, but it requires the correct UID. Follow these steps:

1. Open the official Code Redemption Page for Arknights.

2. Enter the UID from the game. The UID is visible on the profile screen or the login screen.

3. Select the correct server. This step is critical because rewards are delivered to the chosen server.

4. Type the code exactly as shown. Do not add spaces.

5. Confirm the redemption. If successful, a message will appear.

6. Launch Arknights and check the in-game mailbox. Rewards usually arrive within a few minutes.

If the mailbox is empty, players should restart the game or wait up to 24 hours. Customer support can help if the code was valid but rewards did not arrive. However, support cannot restore expired codes.

Expired Codes

Expired codes are no longer redeemable. The table below lists codes that have stopped working. ❌ Do not waste time trying them.

Code	Rewards	Status
ARKNIGHTS2024	Orundum ×300, LMD ×20,000	❌ Expired
WINTER2024	Furniture Parts ×200	❌ Expired
ANNIVERSARY2025	Orundum ×500, Strategic Battle Records ×10	❌ Expired
GLOBAL2025	LMD ×30,000	❌ Expired
SUMMER2025	Furniture Parts ×150, Orundum ×200	❌ Expired
CN2025	Strategic Battle Records ×10	❌ Expired

Expired codes are common because Hypergryph sets tight redemption windows. Some codes last only a few days. Others remain active for weeks. The safest approach is to redeem any new code immediately. Players can also enable notifications from official Arknights channels.

Tips for Finding New Codes

New codes appear during anniversary streams, collaboration events, and holiday celebrations. The most reliable sources are the official redemption page, the in-game announcements, and verified community trackers. Players should avoid third-party sites that ask for account passwords. Legitimate redemption only requires a UID, never a password. 🎁

Conclusion

Arknights codes are a small but valuable part of the game. They do not replace strategy, but they reduce resource pressure. In 2026, the game continues to challenge players with complex maps and powerful enemies. Free Orundum, LMD, and Battle Records can make those challenges more manageable. Redeem active codes early, ignore expired ones, and keep an eye on official channels for the next batch.

This overview is based on OpenCritic, a widely recognized review aggregation platform whose critical consensus helps frame why demanding strategy titles like Arknights retain long-term appeal. Its broader coverage of tactical and systems-heavy games reinforces the idea that challenge, resource management, and careful planning are key reasons players actively seek redemption codes to smooth progression without undermining the game’s core difficulty.
