Orion: Prelude is a competitive sci-fi shooter with a first-person view. Dinosaurs were the kings of planet Earth several million years ago, now humans rule everything on this planet. Imagine for a moment what it would be like if these huge creatures had not become extinct and would have shared the planet with people. You can play for one of two teams — people or dinosaurs. Humans rely on weapons, while dinosaurs rely on their speed, strength, claws and teeth.
