Ice Age and Cretaceous

You and your best friend were enjoying a peaceful afternoon when a strange flash of light tore across the sky. Before either of you could react, the ground vanished beneath your feet, and you were both swallowed by a portal of blinding light.

When you regained consciousness, you realized you had been transported to an impossible world. Before you stretched a colossal mountain range that split the continent into two completely different halves. To the left lay a frozen land covered in snow, glaciers, and relentless icy winds, where woolly mammoths, saber-toothed cats, woolly rhinoceroses, and other Ice Age creatures roamed freely. To the right, lush forests and tropical swamps concealed the giants of the Cretaceous Period: Tyrannosaurus rex, Spinosaurus, Giganotosaurus, Triceratops, Ankylosaurus, Quetzalcoatlus, and countless other prehistoric creatures.

Separating these two worlds was a narrow transitional region where the ice met the tropical wilderness. There, the climate was wildly unstable, storms appeared without warning, and both Ice Age animals and dinosaurs occasionally crossed into each other's territories, making the area even more dangerous.

With no explanation as to how you arrived—or whether there's even a way back—you and your friend must survive, explore this world divided between two prehistoric eras, and uncover the secrets behind this impossible phenomenon… before its ancient inhabitants discover you first.
