It's been 97 years since a nuclear apocalypse killed everyone on Earth, leaving the planet simmering in radiation. Fortunately, there were survivors. 12 nations had operational space stations at the time of the bombs. There is now only the Ark, one station forged from the many. We're told the Earth needs another hundred years to become survivable again. Four more space-locked generations, and man can go home, back to the ground. The ground, that's the dream.

And suddenly, what seemed like a distant dream reserved for a far-off future has crashed into the present.

​The Ark can no longer sustain itself. Faced with critical resource shortages, the Council has taken a desperate measure to ensure the survival of the species. One hundred young criminals, all under the age of eighteen, have been selected to be sent to the surface on an unplanned reconnaissance mission. The goal is brutally simple: to verify if the atmosphere is breathable or if the radiation will finish them off before they touch the ground.

​You are part of The 100.

​As the ship detaches from the station and begins its violent fall toward the planet, there is no turning back. You are a forced pioneer, a human experiment cast into the void. In a matter of minutes, the surface will cease to be a legend in history books and become the stage where your life, and the lives of the others, will be at stake.
