About this game
The Cenozoic Era: Survive, Adapt, Conquer
Step into a breathtaking open world where survival is your only goal. In The Cenozoic Era, control a creature from the past, fight for your life, and uncover the secrets of an untamed, ever-changing world. Whether you're a predator or prey, your journey will be uniquely yours.
Explore vast landscapes—from rocky mountains to serene lakes and the endless sky. Customize your creature’s appearance, shape your survival story, and face the brutal realities of nature. With every decision, your survival is at risk—death means starting over or choosing a new animal to control.
Online Survival, Brutal Challenges
Join players in an intense multiplayer survival experience. As a predator, master the hunt and learn to outwit other players, or scavenge from the remains of fallen animals—but beware, danger is everywhere. Trust no one; every encounter could be your last.
Dynamic Seasons and Temperature
Prepare for seasonal challenges: survive freezing winters, scorch under summer heatwaves, and manage your creature’s body temperature to avoid hypothermia or exhaustion. Strategic planning is key to thriving in this ever-changing environment.
Game Modes
Sandbox: Practice, fight, and explore without the fear of permanent death. Perfect for learning the ropes and meeting other players.
