Mesozoic Dawn

Mesozoic Dawn is a multiplayer dinosaur survival game set in a prehistoric wilderness. You begin as a vulnerable juvenile and forage, stalk prey and grow. Its “Spawn & Evolve” system lets you develop beyond your starting lineage and work toward becoming an apex predator.

The prehistoric world

The world spans sea, land and air, with over 70 prehistoric species in a low-poly style. Each creature has its own survival instincts. Neutral and hostile AI herds follow independent behavior, and during special seasons they gather for large migrations that can bring both danger and opportunity.

The world is divided into climate zones, and different creatures have specific temperature and humidity requirements. Finding a suitable area can help you survive and grow faster.

Growth and evolution

Evolution follows the system “Growth + Spawning = Evolution” rather than an XP bar. You consume highly nutritious food and reproduce to unlock more powerful, higher-tier predators.

Survival and combat

Hunger, thirst, stress and injury can damage your stomach, lungs and heart, reducing their conversion efficiency. Temperature, humidity, oxygen and energy also affect survival.

Combat combines skill buffs, attack penetration and defensive toughness with localized damage: hits to different body parts have different damage multipliers and defensive effects. True damage bypasses armor and reduces health directly; it also builds trauma that inhibits heart regeneration, even when the target’s armor remains intact.

Nests and lineage

You can reproduce asexually or find a mate. Environmental temperature determines offspring gender, and males have natural advantages in size, attack and defense. Gather stone and wood to build a nest, which serves as a safe haven and respawn point.

You can manually brood eggs to double their hatching speed and build generational accumulation. Offspring inherit strong genes from their parents, while random fluctuations can push their attributes beyond their limits. Across generations, targeted brooding enhancements let you shape a distinctive lineage.

AI companions and offspring

You can find a wild dinosaur of the same species and opposite sex, then build affinity by staying close to tame it as an AI companion. Eggs you lay can also hatch into AI offspring that follow orders and fight alongside you.

Commands for companions and offspring include Follow, Attack Target, Standby, Defend, Protect and Evade. AI companions can search for enemies, assess threats and carry out tactics on their own.

Multiplayer

You can hunt with other players or fight rival groups over territory, water and food. The game supports community servers and Steam P2P LAN matchmaking.
