In 66 million BCE, a massive asteroid impact wiped out non-avian dinosaurs and 75% of Earth's species, clearing the path for mammals to dominate. As a time traveler, you intervene in this cataclysmic event, potentially saving dinosaurs or reshaping life's trajectory through survival, evolution, and ecological chaos.
Deflect its path, mitigate the blast, or let it strike—will you preserve a dinosaur-dominated world or doom emerging life to new horrors?
What if the KT event never happened, allowing dinosaurs to evolve into intelligent species and reshaping modern Earth's biodiversity?
