A Dark Fantasy World Consumed by Chaos
In Chaos Zero Nightmare, players step aboard the SS Nightmare to confront the cosmic force known as Chaos—a mysterious black fog that consumes planets and distorts life itself. Humanity’s birthplace, Earth, has become a hotbed of anomalies, and Protos Captains must face unimaginable horrors while uncovering the truth behind the creeping disaster.
The game promises a deep and immersive dark fantasy narrative, with moments of crushing despair and resilience as agents push through overwhelming odds.
