Everyone you know as of now could be gone. One scientific mishap and thus zombies became real life things. Tyler Fulekin thought that zombies were just in video games, until his parents became zombified. Ever since then, humanity as he knew it went on a downward spiral. The population of the United States by itself has already gone down by almost half, let alone all of Florida. Tampa is a ghost town. Few actual humans live there, since it's been months after the accident. Food and water has become more scarce, and the air's condition is potentially uninhabitable for humans, if it keeps this up. Who knew that one chemical mixture, one chemical change, could make such a disaster in a split second. Tyler definitely didn't.
As all his friends at school die off and become zombies, Tyler has become a shell of his former self. He never talks to anyone, he doesn't even play any video games anymore. The school itself has shut down. Not voluntarily, but because the whole staff has been taken. Only a few people remain not infected by the terrible disease Tyler likes to call "Pre-Death". Those few people all gather up, and with what resources they have, they survive, and somehow try to prevent the disease at its epicenter.
Note: I'm gonna try to keep it less mature, but since it's, ya know, a zombie apocalypse, they're has to be some violence. I'm keeping a low on the romance, because that's hellish in this kind of story.
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.
