Smilegate's grim fantasy RPG casts you as the commander of the SS Nightmare, charting a course through a shattered cosmos warped by a reality-twisting black mist. Guiding your crew through these perilous frontiers involves mastering tactical card duels while navigating heavy moral dilemmas that directly alter your persistent campaign records.
Steering into such an unforgiving void calls for every advantage you can muster. Securing stockpiles of Crystals and Signal Amplification Anchors grants a welcome influx of valuable assets, giving your expedition an extra boost as you push deeper into the encroaching gloom.

What are Chaos Zero Nightmare codes?
Chaos Zero Nightmare codes are promotional gift codes from the developers. Entering one in the game sends free items to your account, usually through the in-game mailbox. Each code can only be claimed once per account, and once it expires it stops working for everyone.
How to redeem Chaos Zero Nightmare codes
- 1Open Chaos Zero Nightmare on your phone and finish the tutorial — the gift code option often stays hidden until you do.
- 2Tap your avatar or profile picture, then look for Settings. Most games put a Gift Code, Redeem or Exchange button there.
- 3Copy a code from the active list above and paste it into the box.
- 4Confirm, then check your in-game mail to collect the reward.
- 5If you can't find a code option, check the game's official social pages for its current redemption method.
Codes are case-sensitive. Some games only redeem codes on a website or from a specific server, so if the in-game box rejects a fresh code, double-check you're on the right server.
Why isn't my Chaos Zero Nightmare code working?
- The code has expired. Mobile gift codes often last only days.
- It was typed with the wrong capitals or an extra space — paste it instead of typing.
- You've already claimed it on this account.
- It's tied to a level, region or server you don't meet yet.
- The reward is waiting in your mailbox rather than appearing instantly.
