Deep in the underbelly of Shadow City, a secret society of shadow-dwellers has been gathering in the dead of night to play a most illicit game of soccer.
Using their mastery of darkness, stealth, and the art of ninjutsu, they kick, dodge, and weave through a field of razor-sharp obstacles, all while avoiding the gaze of the city's elite.
But beware, for the rules of Shadow Box are simple: stealthy rules are everything, and those who break them shall face the wrath of the Shadow Box.
Tournaments are held regularly, where the best shadow-soccer players gather to test their skills and claim the coveted Golden Sash of Stealth.
But it's not just about the thrill of victory, nor the agony of defeat - it's about the art, the skill, and the sheer, unadulterated shadow of it all.
Shadow Box Heroes are born in the depths of this most unlikely of games.
Will you join the shadows, and take the field? Join the Shadow, if you dare.
