In the gritty, steam-powered expanse of Torch City, an oppressive occupying force known as the Machine Legion has crushed the once-thriving civilization of its animal inhabitants through military conquest. Rayton, a battle-hardened rabbit who served as a pilot during the doomed resistance, has spent years in self-imposed exile, attempting to distance himself from the horrors of war. When circumstances force him out of hiding, he reclaims a formidable mechanical gauntlet constructed from salvaged combat gear and descends into the industrial underbelly of the occupied metropolis to confront the Legion's forces and expose the hidden machinations driving their tyrannical rule.
