How do I redeem Chaos Zero Nightmare codes?

You have to play through a good chunk of Chaos Zero Nightmare before you can redeem any promo codes.

Once you gain access to the Lobby, click through the tutorial that leads you to the next story mission. Instead of triggering the next right, click the screen to clear the prompts, then back out to the Lobby.

From here, open the menu at the top-right, click the Settings icon, then the Account Settings tab at the bottom. Here, you'll see the "Register Coupon" button in the middle. Click it, enter a Chaos Zero Nightmare code into the box that appears, and click OK.

If your CZN coupon was valid, the rewards will appear in the in-game mailbox. The mailbox can be accessed via the top button in the main menu.

Why won't my Chaos Zero Nightmare codes work?

On launch day, the Chaos Zero Nightmare Discord server was rife with complaints about CZN codes not working.

The larger community believes it's down to the code redeem system being bugged or down for maintenance, though no official announcement has come from the game team to confirm or deny the claims.

Because of this, it's just as easy to believe that any CZN codes in circulation around the game community are simply false, invalid, or only work on the Asia server.

How do I get more Chaos Zero Nightmare codes?

New Chaos Zero Nightmare codes are expected to drop via the game's various social media pages.

If you don't want to scan a bunch of these every day, or set up myriad notification systems, the Chaos Zero Nightmare Discord server is the next best place to look. Most of the game's social media posts appear here, too, collating every campaign into a single platform.

If Discord isn't something you want to deal with, either, just check back here each time you play. We scour social platforms daily to find new Chaos Zero Nightmare codes to add to the list above. We also test existing codes and remove expired codes, ensuring you don't waste time attempting to claim codes that no longer work.
