The Cenozoic Era

The Cenozoic Era is an online survival game where you control an animal in a changing world. Play as predator or prey, explore landscapes ranging from rocky mountains to lakes and open skies, and customize your creature’s appearance. Death means starting over or choosing a new animal to control.

Survive the wild

As a predator, you hunt and try to outwit other players. You can also scavenge from fallen animals, but every encounter carries danger. Seasonal conditions include freezing winters and summer heatwaves; manage your creature’s body temperature to avoid hypothermia or exhaustion.

The world has dynamic seasons—spring, summer, fall and winter—and changing weather, including rain, thunderstorms and snow. Snow tracks, AI creatures such as rabbits and fish, and seasonal food behaviors, such as deer eating bark in winter, also feature in the world.

Game modes

• Sandbox: practice, fight and explore without the risk of permanent death, and meet other players.
• Survival: grow from a young animal into a survivor, hunt and face other players as you fight for dominance.

Creature development

Creatures grow seamlessly and have a skill tree. You can breed them, breed mutations and customize their skins with color packs. Server settings can be customized for different play styles, and servers can assign roles and colors to players. The game supports mods and the Steam Workshop.

Events and rewards

Events include leaderboards and rewards, breeding competitions, holiday events and rare skin unlocks.
