In 2147 AD, a disaster called the "Star Catastrophe" swept across the world, turning the surface of the earth into a dead wasteland. A mysterious energy called "Eclipse Radiation" has eroded all land, making it impossible for humans to survive outdoors.
Just when humanity is on the verge of extinction, the mysterious "star orbit system" descends on the world. Each survivor is assigned a "starter train" - an armored train suspended on abandoned railroad tracks, becoming humanity's last mobile shelter.
All trains lead to one ultimate goal: the legendary "Garden of Eden" - the only pure land that has not been eroded. But to get there, you must pass through 10,000 stations and undergo endless tests.
