Chaos Zero Nightmare

Chaos Zero Nightmare puts you in command of the SS Nightmare, blending tactical, card-based combat with a somber, character-driven narrative that evolves across runs. You lead a roster of agents through branching routes and crisis encounters where stress, consequences and careful resource management determine survival; choices you make in one attempt alter future runs through persistent save data. Players who enjoy strategic decision-making, replayable roguelike structure and strong atmosphere will find this title rewarding: every mission becomes a test of risk versus restraint, with meaningful consequences and memorable character moments to uncover.
