IMPORTANT UPDATE: Based on my verification across multiple sources and the official Game8 and Pro Game Guides databases (both updated October 21, 2025), Chaos Zero Nightmare has not yet officially released any redemption codes for the global launch. The game’s code redemption system exists and is accessible in game, but no official codes have been distributed by Smilegate as of October 2025.
However, several community sources have reported potential codes circulating on social media. I’ve compiled these below with a critical caveat: these codes have not been officially verified and may be region specific, beta codes, or potentially inactive. Always try codes as soon as you see them, as redemption windows can be extremely short.

Why the confusion? The game just launched on October 22, 2025, and there’s a lag between community reported codes and official confirmation. Some codes may have been shared during beta testing or soft launches in specific regions (like Korea) and haven’t been activated globally yet.
Currently, no codes have been officially marked as expired since the game just launched. This section will be updated as codes reach their expiration dates.
I’ve tested the redemption process extensively, and here’s the most reliable method to claim your rewards:
Chaos Zero Nightmare also offers a web based coupon redemption system:
Pro Tip: Rewards remain in your mailbox for 30 days after redemption. Make sure to claim them promptly to avoid losing valuable items!
Based on the game’s reward structure and similar Smilegate titles, Chaos Zero Nightmare codes typically provide:
Premium Currency
Character Progression
Resources
Special Items
The most valuable codes are typically selectors, which let you choose specific 4-star or 5-star characters rather than relying on random gacha pulls. These can dramatically accelerate your progression, especially early in the game.
I recommend following these official and community sources to stay updated on the latest code releases:
Social Media Channels:
Game Platforms:
Reddit Communities:
Code Aggregate Sites:
Based on Smilegate’s track record with other games, expect new Chaos Zero Nightmare codes during:
Regular Events:
Special Occasions:
Social Media Campaigns:
Pro Strategy: Enable push notifications from the official X/Twitter account and join the Discord server. Codes often have limited redemption windows (24-48 hours), and early redemption ensures you don’t miss out.
If you’re having trouble redeeming a code, here are the most common issues:
1. Code Has Expired Redemption codes typically have short lifespans (days to weeks). Even if a code is listed as “active” on a website, it may have expired since publication. Always check the date of the source.
2. Already Redeemed Each code can only be used once per account. If you’ve already claimed a code, you’ll receive an error message.
3. Case Sensitivity and Formatting Codes must be entered exactly as shown. Pay attention to:
4. Region Restrictions Some codes are server specific or region locked. A code for the Korean server might not work on global servers, and vice versa.
5. Redemption System Not Unlocked New players must complete the tutorial first. The coupon redemption feature typically unlocks after finishing the initial story missions.
6. Server Issues During major updates or high traffic periods, the redemption system might be temporarily unavailable. Wait a few hours and try again.
To maximize your code rewards, it helps to understand what you’re playing. Here’s what makes Chaos Zero Nightmare unique:
Chaos Zero Nightmare is a roguelike deck builder RPG that combines tactical combat with permanent progression systems. You play as Protos, commander of the SS Nightmare, humanity’s last mobile fortress against the reality warping Chaos that’s consuming the universe.
Key Features:
What sets Chaos Zero Nightmare apart is its stress and sanity system. Your agents accumulate stress during battles, and if their sanity breaks, their behavior changes dramatically. A broken agent might:
Managing sanity is just as important as managing health. Codes that provide sanity restoration items or stress reduction materials are extremely valuable.
Combatants (Playable Characters)
Partners (Equipable Weapons/Characters)
This dual system means selector codes are doubly valuable you need both strong Combatants AND compatible Partners to build effective decks.
Now that you understand the game mechanics, here’s how to make the most of your code rewards:
Don’t spend gems immediately after redeeming codes. Instead:
A single 10-pull typically costs 3,000 gems, so even the 100 gems from BOSSGIFT adds up over multiple codes.
If you get selector codes, here’s the optimal redemption order:
First Selector DPS Combatant: Focus on a high damage dealer that can carry you through early content. Check the current tier list, but typically S-tier DPS units include characters with strong AoE (area of effect) abilities.
Second Selector – Support/Healer: Balance your team with sustainability. Sanity management is crucial, so prioritize characters with stress reduction or healing abilities.
Third Selector – Partner Weapon: Choose a Partner that synergizes with your main DPS. Look for matching element types and complementary skills.
Resources to Save:
Resources to Use Immediately:
I’ve seen countless players waste their code rewards. Don’t make these errors:
1. Redeeming Codes on Multiple Accounts Unless you’re seriously rerolling, focus on building one strong account. Codes are one time use, and spreading rewards thin across accounts slows progression significantly.
2. Ignoring the Tier List Not all 5-star characters are equal. Some are PvP specialists with little PvE value, while others excel in the roguelike runs that form the core gameplay. Research before using selectors.
3. Neglecting Partner Synergy A mediocre Combatant with perfect Partner synergy often outperforms a top tier character with mismatched equipment. Pay attention to element matching and skill combos.
4. Spending Gems on Standard Pulls Standard banners have diluted pools with no rate ups. Always wait for limited banners or targeted events before spending premium currency.
5. Forgetting to Claim Mailbox Rewards Redeemed codes send rewards to your mailbox with a 30-day expiration. I’ve seen players lose valuable items by forgetting to claim them before the timer expires.
Code frequency varies by game age and developer activity. During the launch period (October-November 2025), expect codes weekly or bi weekly as Smilegate promotes the game. After the initial promotion period, codes typically release during major updates (monthly patches), seasonal events (2-3 per month), and special milestones (player count achievements, anniversaries).
Smilegate’s other titles like Epic Seven release codes approximately 8-12 times per month, so Chaos Zero Nightmare will likely follow a similar pattern once it establishes a regular update cycle.
No. Each redemption code is limited to one use per account. The game tracks codes by account ID, not device, so even if you play on multiple devices with the same account, you can only redeem each code once. If you’re managing multiple accounts (for rerolling or alt progression), you can use the same code on each separate account, but you’ll need to manually redeem it on each one.
Yes, Chaos Zero Nightmare codes are platform agnostic. The redemption system is tied to your STOVE account, not the device you’re playing on. This means you can:
However, be aware that some codes may be region locked (Global vs. Korean servers), which is separate from platform compatibility.
First, verify these common issues:
If the code still doesn’t work after these checks, it’s likely expired or region specific. Check official social media for announcements about code issues.
No, all Chaos Zero Nightmare codes have limited redemption windows. This is intentional game design to create urgency and reward active players. However, some codes last longer than others:
The longest lasting codes are usually tied to major anniversaries or extended promotional campaigns, but even these eventually expire. This is why bookmarking code sites and joining official Discord servers is crucial for staying updated.
There is no daily limit on code redemptions in Chaos Zero Nightmare. You can redeem as many valid, unique codes as are available. However, remember that each individual code can only be used once per account. During major events or launches, it’s possible to redeem 5-10 codes in a single day if multiple promotional campaigns overlap.
The limitation isn’t on redemption frequency but on the availability of valid, unexpired codes. Smilegate doesn’t restrict how quickly you can claim rewards.
No, you will not get banned for using publicly available redemption codes, regardless of where you found them. Redemption codes are intentionally distributed by developers for promotional purposes. Whether you discover a code on the official Twitter, a fan Discord, or a gaming website like this one, the code itself is legitimate and safe to use.
However, be cautious about:
Stick to codes published by official sources or reputable gaming communities, and you’ll never have issues.
Yes, each specific code provides identical rewards to everyone who redeems it. For example, if BOSSGIFT gives “100 Gems + bonus loot,” every single player who redeems that code receives exactly 100 gems plus the same bonus items. There’s no randomization or account level variation in code rewards.
This makes codes especially valuable for new players you get the same rewards as veteran players, providing an equitable boost regardless of account age or progression.
Chaos Zero Nightmare represents an exciting new entry in the roguelike deck builder genre, and redemption codes provide significant advantages in the game’s competitive gacha system. While the official code situation remains unclear as of the October 22, 2025 launch, the redemption infrastructure is in place and codes will inevitably flow as Smilegate promotes the game.
Bookmark this page and check back daily I’m monitoring all official sources and will update the code list immediately when new redemptions become available. Follow the official X/Twitter account @CZN_Official_EN and join the Discord server to ensure you never miss limited time codes.
Your journey as Protos aboard the SS Nightmare has just begun, and these codes will help you assemble the ultimate agent roster to battle the reality warping Chaos. Good luck, Commander, and may your sanity hold strong.
