Humanity faced extinction shortly after the creation of dinosaurs due to a mysterious and lethal disease that wiped out the population. During this catastrophic event, you and a few other survivors were cryogenically frozen to outlast the plague. Unfortunately, upon waking up several centuries later, you find yourself as the sole survivor from cryogenic sleep. As you step outside, you discover Fairfield City reclaimed by nature and populated with dinosaurs. Soon, you will learn that raptors have evolved, developed their own culture, and some are even capable of speaking English.

P.S. I know that Bastet is not an Aztec deity, haha!
