“Cell Defense” is an app prototype that playfully explores the body’s natural immune defence system.

To counteract inflammation, the player places the body’s own cells on the adjacent tissue in order to recognise and neutralise pathogens. The game principle is based on tower defence games:
As the game progresses, the number and type of invaders varies, but new defensive cell types can be discovered and upgraded.

Although the scientific aspect is subordinate to the fun of the game, the idea is to provide students with easy access to learning about the connections and interactions within the immune system.
