Storyline

Chaos Zero Nightmare: Command agents aboard the SS Nightmare through unpredictable roguelike Chaos runs in a sci-fi world devoured by cosmic horror—build unique decks from character-specific cards, chase wild synergies to break enemies, and manage mounting stress to dodge mental breakdowns that trigger Deep Trauma. Back at base, dive into moving Trauma Code stories revealing each agent's haunted past and personal fears, then hit the Epione Center for tense, choice-driven therapy sessions—counsel them to reclaim corrupted save data and boost bonds, or erase memories for a quick reset (but lose those gains). Every failure hits hard but fuels deeper progression and replayability.
