About the Game
Saurian is a dinosaur survival experience set in Hell Creek 66 million years ago. Players will take control of several extinct species in their natural environment and attempt to survive from hatchling to adult. Staying alive means managing physical needs while avoiding predators and natural hazards in an open world landscape reflecting up-to-date scientific knowledge of the Hell Creek ecosystem.
Features In Saurian
- Survival: Start as a hatchling; eat, drink, and grow to an adult while avoiding predators and hazards.
- Open World: Explore the diverse environments of Hell Creek with accurate flora of that time and location.
- AI Ecosystem: The animals around you have the same needs as you do and will interact with you based on them.
- Scientific Accuracy: Every animal and plant has been rigorously researched to be accurate to currently accepted knowledge.
