Humanity took a blow as the Great War, driven from panicked hunger for resources and crazed drive for power, obliterated the Earth, as hundreds of atom bombs tore apart the planet. However, underground vaults held the last remains of the human race. The vaults each held one goal, some to keep humanity alive, and some to experiment on them like animals. In Vault 46, the residents were kept safe by Vault-Tec and seemingly unharmed by experimentation, until after 170 years in the vault, the residents are told by a mysterious radio call that the outside had turned back to what it had been before the war. Young dweller Zech Taylor was the first to be sent out in search of the world promised by the radio call, but as war had brought, a cruel world separated Zech from his cozy vault life into a wasteland brought by the mistakes of the human race. His mission becomes more than a recon, as more lies in the atom bleached land of post-war Missouri, and his journey in the wastes shows it's true colors, as Zech explores in search of a smeared mission.
Season 4 of The Virus Within
Trinity is familiar with zombies, being one herself, but when strange zombies start appearing, she realizes that the world she knew might be changing yet again.
When a dangerous set of scientific notes are discovered, Trinity and her friends don't realize anything is wrong until a frantic radio call comes in. Unaware of the notes, they race to the south and struggle to determine where the strange zombies came from. The zombies are unlike any ranks previously seen, and they aren't as predictable. Some have new tricks hidden up sleeves, forcing any Stronghold they encounter to quickly adapt to the new challenge or risk being overrun. Secrets never remain hidden, and zombie apocalypses never make life easy.
