Knock and Walk is an illegal and brutal combat sport with roots stretching back to the Last Frontier spaceship. Revived in the Gamma Age by the Jane Mendoza Gang, the fights have become a centerpiece of Firetown's “Shadow District”, drawing high-stakes gamblers and thrill-seekers alike. The sport is notorious for its fatal outcomes and the absence of any meaningful law enforcement intervention due to systemic corruption.

• Origins on the Last Frontier: Knock and Walk originated among rebellious teenagers aboard the Last Frontier. The game was a life-threatening challenge, played in secret and relentlessly pursued by the Guardian Troopers as an illegal activity. Despite its danger, the sport cultivated a reputation for testing courage and endurance.

• Reemergence in the Gamma Age: Thought forgotten during the Beta Age, Knock and Walk reemerged in Firetown after the Great War, adapted into a professionalized, high-stakes betting sport. The Jane Mendoza Gang capitalized on its visceral appeal, turning it into a profitable underground enterprise. Federal Sheriff estimates place the gang’s annual earnings from Knock and Walk bets at 220,000 Kourou. While the game remains a violation of the Civil and Criminal Code of the Federal Confederation, the gang’s system of bribes and kickbacks ensures law enforcement rarely intervenes, allowing the fights to persist as a grim hallmark of Firetown’s underworld.
