The aliens have started an invasion of earth and soon they would become the dominating race on the planet if they are not stopped. Sophie along with the rest of the survivors starts developing a plan that can help to save humanity and this could possibly be her last mission because if she fails then she would not make it out alive. Authors Nicholas Sansbury Smith and Anthony J. Melchiorri have given everything to this series.
Hell Divers IX: Radioactive and Hell Divers II: Ghosts gave the audience something darker to enjoy. This series has an equal amount of excitement in its scenes. The initial parts show the domination of the alien race and then the humans take over with the help of Dr. Sophie. Ending scenes show the sacrificing nature of the human race that makes them superior as compared to the aliens.
