About this game

Enter the microscopic battlefield! Click infected cells to release replication factors that spread along connections to healthy neighboring cells. Each infected cell generates mutation points — accumulate enough to unlock powerful evolution choices: faster replication, stealth dormancy, or immune resistance. The immune system fights back with white blood cells that patrol connections and clear infections. Higher levels feature denser cell networks with more complex topologies, faster immune response times, and shorter infection cooldowns. New mechanics emerge: dormant cells that hide from immunity but cannot replicate, immune alert zones that increase patrol intensity, and core cells that must be infected to complete the level. Strategic evolution choices determine your playstyle — aggressive spreaders overwhelm quickly, while stealth builds survive immune sweeps. Outsmart the immune system, evolve your strain, and achieve full infection of every microscopic battlefield.
