How to Survive at the End of the World 4

Back for one last hurrah, will Sean save New Earth and survive a system instance that's breaking down? When Sean is called upon to enter a Nebula Challenge to save his new home, he doesn't exactly leap into the opportunity. But knowing that he's humanity's best chance at salvation and with loose ends to tie up in terms of Eike's dad, he chooses to once again go into the chaos with Aggi and Jeff. Instead of a simple challenge that he can understand, Sean finds himself caught in the rapid deterioration of the system as he knew it. Now, he doesn't only have to contend with others looking to hurt him; he needs to find a way to deal with the delicate line of a supernatural being calling for his death.
