The plot takes place in a post-apocalyptic world ravaged by a nuclear war. The World Empire's iron-fist control has left people devoid of their freedom and humanity. Despite the strict prohibition on weapons, a rebel crew covertly fights back. They exploit antique firearms as their only weapons while the Empire dispatches contemporary weapons to represent them. The antique firearms are channelled into “Musketeers” and join forces with the rebels, empowering their quest for freedom. The “Musketeers” mount a steadfast opposition against the Empire's powerful and technologically advanced weaponry. Their “Absolute Noble” mode unleashes an invincible force that offers hope to shattered lives.
