According to my history teacher from secondary school, it has been a bit over 3000 years since World War III ended with an absolute nuclear apocalypse. Y'see, history isn't my best subject, so that number may be off, but I could tell you for sure that we all live in anger for our asshat ancestors' mistakes.
The planet we live in could barely be considered Earth anymore. All oxygenous beings live in relatively small domes called biomes that are scattered across the world. The rest of the planet is a fiery wasteland uninhabitable by us Oxygenics, but home to the biggest threat to our existence, the Sulfurics.
According to my biology teacher, the Sulfurics evolved insanely quickly from purple and green sulfur bacteria. Because of that, the Sulfurics use sulfur similar to how we use oxygen. And thanks to all these weird as hell mutations brought by our fucktard ancestors' nuclear apocalypse, they have evolved things such as claws that leak sulfuric acid, calls that can knock humans out, and more recently, superior intelligence and the ability to reverse engineer our technology. I have more interest in biology so I could tell you that for sure.
Yep. We're screwed. I blame that on our shit-for-brain ancestors, their greed, and their inability to think about consequences.
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.
