Oberon 69

You find yourself in a world where the air has become unbreathable and Sun’s light barely reaches planet Earth. With your planet almost desertic, many cities began to be built in other planets of the solar system. But… in Oberon, the fourth satellite, there appeared an strange life form, which did just awake from its lethargy. The worst of all is that these new creatures have started attacking the human populations, even if they are babies!
