What Is Once Human?
Once Human is a post-apocalyptic, open-world multiplayer survival game where supernatural forces and Stardust contamination have reshaped Earth. Players take on the role of a Meta-Human, exploring dangerous zones, gathering crafting materials, engineering secure territory bases, and battling cosmic monstrosities known as Deviations.
Surviving the wilderness requires a steady stream of ammunition, medical consumables, and high-tier equipment. Promo codes released by Starry Studio grant instant access to critical currencies like Starchrom, cosmetic crates, and crafting boosters, giving players a major advantage across PvE and PvP scenarios.

How to Redeem Once Human Codes
To redeem codes in Once Human, you must first complete the opening tutorial. The Events tab remains locked until you complete the Follow Up main story quest. Once unlocked, follow these steps:
Complete the Follow Up Quest
Progress through the prologue story until you complete the "Follow Up" tutorial objective. This unlocks access to the game's event interface.
Open the Main Menu
Press Esc on PC, press the Options button on a controller, or tap the top-right menu icon on mobile devices.
Open Shop Events
Click the Shop Events banner in the top navigation strip. Alternatively, press F3 on your keyboard to open the interface directly.
Access the Redeem Code Screen
Navigate to the Events tab on the left navigation bar, then click the Redeem Code button (or press X on your keyboard).
Enter Code and Claim Rewards
Enter or paste your promo code into the text input box and click Redeem. Your rewards will be credited immediately to your inventory or in-game mailbox.

If you encounter an error when entering a Once Human code, check this troubleshooting matrix to identify the issue:
| Error Symptom | Common Cause | Recommended Solution |
|---|---|---|
| Events Tab Missing or Locked | The tutorial quest has not been cleared. | Progress through the main story until the "Follow Up" quest is marked complete. |
| Redemption Limit Reached | The code has exhausted its global allocation pool. | The creator code has hit its maximum cap. Test the remaining active codes on the list. |
| Invalid Code / Code Does Not Exist | Typo or extraneous whitespace in the code string. | Use the copy button above to paste the exact alphanumeric string without spaces. |
| Already Redeemed | The promo code was already claimed on this character. | Most Once Human codes can only be claimed once per account or seasonal character. |
