New York is no longer just a city. Beneath its streets, abandoned stations, and forgotten sewers lies a hidden world where mutants, ninja clans, and scientific secrets coexist in a silent war.

The mutagen changed everything. It created heroes, monsters, and creatures that no one can fully control. While humans continue their normal lives on the surface, a constant struggle for the city's balance is waged in the shadows.

Four mutant brothers protect what is left of order, but they are not the only ones moving in the dark. New threats, failed experiments, and unknown clans are beginning to emerge, endangering both the human and mutant worlds.

In this city, every decision can change the fate of both worlds… and nothing stays hidden forever.
