The Developer Notes for October 26, 2025 has been released with a thank you message and some info on improvements and new contents for Chaos Zero Nightmare (CZN). See the details of the Developer Notes in this guide!
List of Contents
The developers are making effort on addressing the feedback for the Story from the community. They plan to enhance the immersion and strengthen the emotional connection with the characters and the world.
| Story Feedback Message |
|---|
| In particular, we’ve received a lot of feedback about the story—some of you have expressed a desire for a darker, more harrowing tone, and for deeper insights into the characters’ inner struggles. We understand that many players are looking for a more tragic and immersive world. Our scenario team has been closely reviewing all your feedback since the pre-launch playtest in September, and we’re making every effort to ensure that the quality and direction of the story align with your expectations. We’ve also had extensive internal discussions about aspects of the lore and narrative that didn’t fully meet your expectations. We promise to enhance immersion and strengthen the emotional connection you can build with the characters and the world. |
There will be several improvements regarding the roguelike deck-building. The developers are planning to reduce player fatigue from repeated runs and make the experience more satisfying. There will also be a Contribution Point System incoming that will allow players exchange earned points for Growth Matertials and other rewards.
Additionally, the Card Removal system will be improved to remove unnecessary cards easily and make deck-building a lot smoother.
| Deck-Building Message |
|---|
| As for the roguelike deck-building content—one of the most beloved parts of Chaos Zero Nightmare—we’re preparing several improvements. Our first goal is to reduce fatigue from repeated runs and make the overall experience more satisfying. During Chaos Manifestation, we plan to introduce a one-time Contribution Point system that will allow players to exchange earned points for growth materials and various rewards. We’ve also recognized that focusing solely on battles within Chaos can lead to player fatigue. We’re working to encourage more balanced exploration across multiple regions, which in turn will lead to faster and more efficient deck-building. Additionally, we’re improving the Card Removal feature—one of the core mechanics of deck-building—to make it easier to access and use, thereby reducing unnecessary effort and creating a smoother gameplay experience. |
A new content, Galactic Disaster Season 1, will be coming soon in Chaos Zero Nightmare. A detailed video guide will release soon to introduce this new content.
| Galactic Disaster Season 1 Message |
|---|
| The first season of Galactic Disaster is just around the corner. As this marks our first major update, we’re preparing a detailed video guide to share more specific information with you. Please look forward to it. We’re always listening to your feedback and taking your thoughts to heart. We’ll keep reflecting on them carefully and do our best to deliver a better, more enjoyable experience. As a token of our gratitude to all Protos who have been playing Chaos Zero Nightmare, we’ve prepared a small gift. Thank you once again for your continued support. Have a wonderful weekend—and see you in Chaos. |
