The adventures of Xero centre on his search for his half-forgotten and pregnant girlfriend, Donna. What's worse is that he's stuck in a doomed reality he doesn't even know he's trapped in: a subterranean Mall designed to incubate humans until they are sacrificed. As Xero pursues Donna, he unravels a monstrous conspiracy spanning back before an apocalypse he does not even know happened. Xero discovers that his life in the Endless Mall is really just a waiting game in a sacrificial bubble. His plunge down the rabbit-hole will lead him further away from his droll, comfortable life and challenge him to fight against this mega-structure and the malevolent forces behind it.
