What would you do if you suddenly became 2 cm tall?
"In an alternate universe there is a galaxy very similar to our galaxy. In that galaxy there is a star very similar to our Sun. Circling that star is a planet very similar to our Earth. On that planet there are oceans, land masses, plants and animals very similar to what we find on Earth. Among those animals there is a very smart species of hominids very similar to humans.
"And those hominids that are so very similar to us are governed in a very similar way.
"Only on the other planet, unlike our Earth, the governments are mostly controlled by evil men and women who commit unspeakable crimes against the population of the planet. Yet the people of that planet are lazy, apathetic, and complacent. They are too obsessed with sports, entertainment, and consumerism to pay any attention to what the evil leaders of the planet are doing.
"Of course this could never happen here on Earth.
"On this similar planet in an alternate universe, the evil leaders hired mad scientists to create a deadly pandemic. Their goal was to kill the majority of the population of the planet so that the abundant resources would be entirely available to the elites and their loyal servants."
This is a game where a tiny percentage of the population in an alternate universe survived a sinister conspiracy aimed at killing 99% of the people living on the planet.
Your Character will be one of the Survivors who was not killed by the conspirators, and now must find a way to live in a harsh environment and then seek revenge against the leaders who betrayed you!
