Primeval

Primeval: A Persistent Prehistoric Sandbox
Play as one of 67+ dinosaur and prehistoric species — from hatchling to apex predator — solo, or on servers holding up to 150 players, with progress that carries over between both.
One World, Two Ways to Play
Grow a hatchling to adulthood safely in single-player, then bring that same creature onto a 150-player server to hunt, defend territory, and build a legacy. Retreat back to single-player any time for a session with zero lag and zero raids. Growth, talents, and stats carry over either way.
A Full Life Cycle
Start as a vulnerable hatchling and grow into an apex predator, earning evolution points to unlock talents and traits that shape how your creature plays. Build nests, gather resources to strengthen your brood, and hatch the next generation.
Coordinated Pack and Herd AI
Herbivores form defensive herds. Predators hunt in coordinated packs. It's not a world of animals wandering in circles — creatures work together, the way they would have.
67+ Playable Species
More species than any other dinosaur survival game, spanning land, sea, and sky:
Apex Carnivores: Giganotosaurus, Spinosaurus, Allosaurus

Heavyweight Herbivores: Argentinosaurus, Triceratops, Ankylosaurus

Marine & Aerial Terrors: Megalodon, Tylosaurus, Quetzalcoatlus

Unique Prehistoric Wonders: Anomalocaris, Titanoboa, Dunkleosteus

Built by One Developer
Primeval is built and maintained by a single developer, with regular updates adding new species and mechanics.
