Systematic Immunity Systematic Immunity is a challenging precision platformer set inside the human body...and not a particularly healthy one either. This body has been infected by a big, nasty bugger of a germ, who is making it his business to spawn many more germs as fast as he can. You and your mob of 20 white blood cells must put a stop to his shenanigans at all costs!
