This is a hunting dinosaurs game whose goal is to protect primates (our ancestors) from dinosaurs of the Jurassic era. You have to keep alive primate who will be attacked for dangerous dinosaurs (T-Rex, Spinosaurus, Raptor, Triceratops, Brachiosaurus, Pteranodon, Stegosaurus, Dimetrodon, Paradophosaurus, ...). You will have many weapons, ammo and bullets to use for preserving primates alive. And you will have to keep you alive alone yourself. You can use different weapons, and you can take one in each hand. You will have missions with different difficult levels. You will feel danger and feel responsibility for your life and that of the other primates at all times.
