Life on the Edge

Life on the Edge is an educational tower defense game in which you play as a cell defending itself from pathogens. Place towers to protect the cell, survive changing environmental conditions and maintain homeostasis. Fight through five levels to face the COVID-19 virus.

Defend the cell

Place key towers in strategic locations to protect the cell from a variety of pathogens. You face different enemies across the levels, culminating in a battle against the COVID-19 virus.

Learn about biology

The game introduces concepts in cellular biology and immunology, showing how cells defend themselves from viruses and bacteria and survive through interconnected biological systems.

Experiment in the lab

Sandbox mode lets you experiment with how a cell maintains homeostasis, adapts to environmental changes and defends against pathogens. A built-in encyclopedia covers cell structures, receptors, pathogens and bacteria.
