Germ Patrol

Germ Patrol is a game from Texas Instruments where you must defend the external membrane of a cell from an onslaught of germs as they try and enter. You take the role of a sponge type material which will absorb the germs as they attempt to enter the cell membrane. Once they are caught a germ is counted a captured. If a germ passes through the membrane it is counted as escaped.

Who knew germ warfare was so much fun!
