Genocide on the Infinite Express

<p><strong>A man with no name and no memory finds himself on board a train of infinite length filled with corpses. All of the corpses are clones of himself dead versions of him and no two are exactly the same. They have different haircuts or beards dyed wild colors; some have tattoos or piercings or scars missing or multiple limbs or weirder still are a completely other species... there are dwarf versions of him and dinosaur versions of him and even cartoon cereal box mascot versions of him all gruesomely murdered. Who is he who are they who murdered them and why? What else can he do but walk and hope to find answers to the ultimate murder mystery somewhere amongst the endless corpses?</strong></p>
