Smilegate Megaport has officially launched global pre-registration for Chaos Zero Nightmare, a new dark fantasy RPG set in a world engulfed by chaos. Available now on Google Play and the App Store, players who sign up early will receive 4★ combatant Amir and other exclusive in-game rewards when the game launches.

A Gritty, Narrative-Driven Dark Fantasy Experience

Set aboard the SS Nightmare, Chaos Zero Nightmare drops players into a crisis where a mysterious black fog—known only as Chaos—devours entire worlds. Earth has become the epicenter of a terrifying phenomenon. As the ship’s Captain, you’ll face shifting realities, collapsing agents, and twisted creatures emerging from “The Blue Pot”—a chaotic zone born on Earth.

This isn’t your typical RPG. Every choice shapes your “Save Data,” evolving both the story and gameplay in real time. You’ll need to think fast, react smarter, and make tough calls to survive.

Tactical RPG Meets Roguelike Strategy

Combat in Chaos Zero Nightmare is tactical and unforgiving. It’s played through a unique card system where each move carries weight. You’ll build strategies on the fly as the battlefield changes with every run. Each attempt offers a different path—and that’s where the thrill lies.

The game features a stunning 2D art style and expressive animations, backed by a fully voiced cast. It’s designed to immerse players emotionally while keeping them on edge.

How to Pre-Register

Pre-registering is simple—and worth it. Head to the Google Play Store or App Store (coming soon) search for Chaos Zero Nightmare, and tap the pre-register button. You’ll automatically receive rewards like Amir, a 4-star combatant, at launch.

While there’s no confirmed release date yet, you can follow the game’s official social media accounts and website for the latest updates.
