Chaos Zero Nightmare Codes (June 2026)

Chaos Zero Nightmare is a roguelike deck-building RPG from Smilegate Holdings, set in a future where a spreading corruption called Chaos has consumed entire planets, leaving the survivors to fight back from aboard massive ships. Developer-issued codes hand out Crystals, Tears of God, Signal Amplification Anchors, and Multidimensional Alignment Materials — all resources that feed directly into character upgrades and banner pulls.

How to redeem Chaos Zero Nightmare codes

The coupon registration option only becomes available after completing Chapter 1, Episode 4. Players who haven’t reached that checkpoint won’t see the option in their account settings. There are two separate redemption paths depending on your platform.

Android and PC

Launch Chaos Zero Nightmare and reach the main lobby.

Open the Settings menu via the gear icon in the top-right corner of the screen.

Select the Account Settings tab, shown as a silhouette icon on the left side menu.

Tap Register Coupon and type or paste your code into the text field. Codes are case-sensitive, so check for stray spaces before confirming.

Tap OK. A confirmation message appears on screen when a code is accepted.

Open the in-game mailbox and tap the reward message to collect your items.

iOS

Visit the official Chaos Zero Nightmare coupon redemption page and sign in with your Stove account. Use the same login method you use inside the game — Apple ID, Google, or otherwise.

Type your code into the input field and click Register.

Open Chaos Zero Nightmare, navigate to the in-game mailbox, and tap the reward message to claim your items.

Note: Rewards land in your mailbox rather than your wallet automatically. They remain claimable for 30 days after registration, so tap the message to collect before they expire.

Where new codes are released

Smilegate Holdings typically drops new codes around major content updates, anniversary milestones, and developer livestreams. The official X account (@CZN_Official_EN), along with the Facebook and Instagram pages, are where most codes surface first. The official Chaos Zero Nightmare Discord server consolidates all social announcements into one place and is worth joining to catch drops quickly. The official coupon redemption page occasionally receives codes directly as well, making it worth checking even when no social post has gone out.
