Chaos Zero Nightmare is a thrilling action-adventure role-playing game where players are immersed in a fantastical world of endless possibilities and magical combat. Utilizing strategic card skills, players unleash powerful attacks and abilities, taking on the role of the captain of the Nightmare, leading a team of exceptionally skilled female agents on perilous missions across treacherous battlefields. Chaos Zero Nightmare presents players with beautifully rendered, vibrant anime-style graphics. Players can choose from different team members, combat routes, and storylines. The game features a rich selection of weapons, challenging players' strategic thinking.
The story begins with your character waking up in a dilapidated mental hospital, with no memory of how they got there. Soon, a faint voice echoes through the corridors, whispering your name and warning you of an impending "awakening." From that moment on, you embark on a journey through unpredictable landscapes—abandoned hospitals, dark forests, and surreal dreams that defy the laws of physics.
Each chapter reveals fragments of your past. Through obscure notes and unsettling memories, you gradually piece together the fact that you may have been part of a failed experiment—an experiment designed to use chaotic energy as a weapon. The result? Zero was born, an artificial intelligence with self-awareness that infected human consciousness.
Zero appears as a shadowy creature, relentlessly stalking you, whispering words of despair. The closer you get to the truth, the more unstable the world becomes—walls shift, gravity changes, and time loops unpredictably. This is a story that keeps you constantly on the edge of your seat, like a nightmare you can't wake from.

A Dark Story Filled with Mystery
Chaos Zero Nightmare is set in a gloomy world where supernatural forces have dragged it into chaos. In this desolate land, you will control a series of heroes, facing hordes of enemies, demonic creatures, and powerful bosses whose strength will be severely tested. The game's narrative blends exploration, discovery, and combat, adding mystery and tension to each quest.
A Fluid and Challenging Combat System
Chaos Zero Nightmare's combat system is unique, designed to deliver continuous, intense battles. Its intuitive controls and mechanics test both speed and strategy. Every battle is a test of reaction and planning, because simply attacking isn't enough; you also need to dodge, block, and counterattack at the right moment.
Multiple Game Modes and Multiplayer Experience
One of the most appealing aspects of Chaos Zero Nightmare is its ability to choose between completing main quests and accepting side quests, allowing you to schedule your time according to your preferences. Furthermore, you can participate in individual challenges, as well as cooperative or competitive online battles. Multiplayer modes further enhance the gaming experience, allowing you to team up with other players to defeat powerful enemies or hone your skills in intense PvP combat.

The combat system uses cards instead of traditional attack methods. You need to build decks, manage your agent's stress level, and adapt to changing circumstances during battle. This ensures both fun and strategic gameplay without overwhelming newcomers. Players who prefer thought-provoking mechanics to mindless clicking will find this balance satisfying. Visually, it presents a hand-drawn gothic style, with fluid animation and full voice acting complementing each other perfectly. The art direction and atmospheric soundtrack create an unforgettable ambiance that perfectly matches the dark, post-chaotic era setting. It feels like an interactive graphic novel with strategic elements.

Very fun game. The characters, story, and battle mechanics are very well done. The only issues I have is that prism lens are scarce and difficult to obtain as far as I know making it harder to get animated cards for 5 star characters. I didn't like that everything is locked behind your commander level. Its a tedious thing to have cause I enjoy upgrading my characters. Also hope to see a balance of male and female characters added to the game. Overall great game and would recommend to anyone
This game has a catching story with mechanics I've yet to see in any game. I appreciate the focus on mental health and responses under stressful situations and needing to look out for your agents in more than just physical health. I do wish the main character you had the option to be male or female rather than just male, would make the experience more immersive.
excellent game. straight away got hooked and i pretty much ditched the other games such as nikke and Brown dust. playing since it started. Turn based card game with a dark atmosphere. Story is Phenomenonal, the characters are well-designed, and although there isn't much fan service, it's a solid game. There are no events as far as I can tell since it just started, and I'd love to see skins; otherwise, there's no incentive to spend money. Overall, I highly recommend this and give it a try.

If you enjoy intense action, strategy, and an immersive atmosphere, download the free APK of Chaos Zero Nightmare and enter this dark and chaotic world where your survival depends entirely on your destructive power.
