Cellf Defense

About Cellf Defense

Cellf Defense puts you in charge of a cell’s immune system. Invading viruses and bacteria enter from one side and move toward a vulnerable structure. You click to place immune units—like macrophages or antibodies—along their path. Each unit attacks automatically, but you must choose where to station them and when to upgrade their power or range. Defeating enemies grants resources, which you reinvest in new defenders or stronger upgrades. The challenge escalates across multiple levels, with faster and tougher waves. Success requires balancing immediate defence with long-term resource planning.
