One morning, ten billion people wake up aboard speeding trains in a wasteland.
On both sides of the tracks lies a fog-shrouded wilderness. Every day, they face three junctions where they must choose a route, and get three chances to scavenge with a grappling hook.
The fog conceals supplies, but also deadly mutated abominations.
Jiang Sui is betrayed and cast out by a female teammate from the start, but unexpectedly binds with two absolute talents.
While everyone else hooks up scrap metal and monsters, he casually snags blueprints for core technology.
While others despair at junctions and wait to die, he follows the hidden prompts before him and races ahead.
[Turn left ahead to find an abandoned cryogenic pod containing a genetic enhancement serum.]
[Continue straight ahead to encounter an iron beetle nest. Recommendation: use the train's main cannon to blast it flat.]
While the other survivors shiver on hand-pumped carts and sell their souls for moldy bread, Jiang Sui's train has already been rebuilt and evolved into a steel behemoth a kilometer long.
Nuclear heating, an ecological farm, Gauss machine-gun turrets, all-terrain tracks...
His former teammates watch the steel behemoth roar past and regret it so much they could tear their hair out.
Jiang Sui leaves them with one shrinking taillight: "Keep pumping along. I'm heading to the last station for hotpot."
