THE BODY IS UNDER ATTACK. From the Lymph Node to the Heart, real pathogens have invaded every organ. Bacteria. Parasites. Viruses. Kidney stones. Blood clots. Each zone brings new enemies grounded in actual cell biology — every creature, ability, and mechanic is based on how the immune system really works. BUILD YOUR IMMUNE RESPONSE.
