Only the current version so far — new entries appear as the game ships updates.
The body is under attack! Viruses, bacteria and mutant pathogens are invading — and YOU command the immune system.
Microvade is a fresh take on tower defense set inside the human body. Instead of cannons and archers, you deploy living immune cells — Neutrophils, Macrophages, B-Cells, Cytotoxic T-Cells, NK Cells and Mast Cells — each with unique powers, to stop the infection before it reaches the core.
Fight Real Threats
Rhinovirus, influenza, armored coronavirus, splitting parasites, stealth latent viruses, shielded biofilms — and four terrifying bosses, from the antibiotic-resistant Superbug to the final Pandemic Pathogen.
