@Drakeeybro The first one already sounds familiar if you catch my drift but can be made better with a creative premise than the garbage pile of radioactive zombie feces that other zombie stories shat out. Second one is kind of cliché in a sense? It's not that bad sincerely, lot's of possibilities of how that one will go. Can be made spicy if there's other girl characters stranded with the protagonist being male. The last one is not that bad but "everything trying to kill you" will need to have a justification rather than it being a thing without reason that drives the story.
