About Radiation Island
Radiation Island is a survival adventure set in a huge open world. Stranded in a parallel reality as part of the Philadelphia Experiment, you explore the unfamiliar world, survive its dangers and solve its puzzle to return to the real world.
Explore the world
You can follow your own path through vast forests inhabited by wolves, bears and mountain lions. Investigate abandoned villages and old military compounds, where zombies guard tools, weapons and clues to the world's secrets. You can also swim and dive, while avoiding hungry crocodiles.
Survive and craft
Hunt animals, fish and gather fruit to stave off hunger. Mine resources and craft weapons, tools and basic vehicles, or search for hidden treasures, equipment and firearms. Radiation, anomalies, harsh weather and enraged zombies threaten your survival.
Face the elements
The game has a full day-night cycle. Darkness and cold bring additional dangers.
