Chaos Zero Nightmare is a chaos-loop RPG that centers on player choice. Like many titles in the genre, having a head start on resources can be the difference between a smooth progression and a stalled run. Fortunately, the developers periodically release promo codes that provide helpful items to keep your momentum going.
Updated October 2026, this list covers all currently active codes available for the game. These gifts range from common supplies to more specific items like Signal Amplification Anchors. Be sure to redeem these as soon as possible, as many carry expiration dates and others may vanish without notice once the developers rotate their promotions.

How to Redeem Codes in Chaos Zero Nightmare
- Launch the game and reach the main dashboard or home screen.
- Locate the settings menu, typically found via your profile icon or a dedicated gear icon.
- Look for a tab labeled ‘Promo Code’, ‘Redemption’, or ‘Gift Code’.
- Enter your chosen code exactly as it appears in our list.
- Confirm the entry to have the rewards sent directly to your in-game mailbox or inventory.
Why Your Code Isn’t Working
- Case Sensitivity: Most systems require you to match the exact casing of the code, so ensure caps lock is handled correctly.
- Expired Validity: If a code has passed its designated end date, it will no longer grant rewards.
- Typing Errors: Small typos are common; we recommend copying and pasting codes directly to avoid confusion with similar-looking characters.
- Single Use: Codes are typically limited to one redemption per account.
