Steve sees a sign asking for test subjects for an experiment. Not being in a good financial position, Steve enters the laboratory and follows Professor Mortimer into the basement. There he is asked to enter a machine. Steve doesn't realise of course, that said machine will keep him in suspension for thousands of years, leaving him in a world where there is seemingly no sign of humanity left, and strange creatures have evolved and invaded. Steve must survive and try to find any sign of non-zombified humans.
