Skin City has been liberated, offering a flicker of hope to all who live
 in the wasteland—hope that times are changing. But it has been a 
Pyrrhic victory, coming at great cost to the few who remain and seek to 
carry on the fight. War looms on the horizon as the survivors now seek 
to take the fight against the overwhelming might of Thorne Industries.
Rin Takahashi finds herself thrust into the spotlight at the 
forefront of the struggle, one she never wanted, yet she feels 
honor-bound to carry on in memory of a fallen friend. Meanwhile, Marcus 
strives to save the woman he loves from the soulless corporation 
threatening to consume them both. And James Mason nears the end of a 
long road, attempting to make things right after a lifetime in which so 
much went wrong. These three find themselves in a desperate battle as 
they seek to topple Thorne Industries in a war that will shake the 
foundations of the continent.
