The story went that Marty had spent his life exploring the labyrinthine tunnels and abandoned rail lines that crisscrossed beneath Gearhaven. Some claimed he was a former engineer turned urban explorer, while others believed he was a ghostly apparition, doomed to roam the underrail for eternity.
Underrail is brutal to characters who sacrifice Constitution for Speed. One missed dodge, one plasma grenade you didn't account for, and you are paste. But the true "Marty" moment comes from the psychological toll. You are constantly asking yourself: “Can I survive this turn?” The answer is usually, “Only if the RNG gods favor me.”
There is nothing—absolutely nothing—like entering a Dominant difficulty arena fight against impossible odds, surrounded by enemies, and pulling off a turn so complex, so perfectly timed, that you wipe the floor before they get a move. It feels like cheating, but it isn't. It’s just math. Very fast, very dangerous math.
