A mountain range (implicitly the Rockies) infested by the cloned dinosaurs that once populated a defunct amusement park–chief among them a particularly oversized and vicious Tyrannosaurus named Satanus. An agricultural laboratory in Utah where the sole remaining scientist (a caricature of Colonel Sanders) has created an army of creatures based on various corporate mascots, such as the Green Giant and the Michelin Man. The "Judges" of Las Vegas, now completely corrupted by the Mafia and running the entire city on literal life-and-death gambles. After fourteen days (and many deaths), Dredd's party reaches Death Valley, where Tweak reveals that he is not only sapient and fully capable of human speech, but the leader of his home planet. This planet, rich in diamonds and other valuable minerals, had been discovered by human astronauts many years ago; through their innate precognitive abilities, Tweak and his fellows had determined that any human interest in the planet would mean exploitation and disaster, and resolved to hide themselves. When a fluke allowed the astronauts to capture Tweak's own children and mate, Tweak surrendered himself, all the time pretending to be an unintelligent animal to minimize their interest; while this successfully saved his planet from further human contact, it resulted in his family being sold into slavery, and ultimately being killed. While sympathetic, Dredd is also suspicious of Tweak's motives in relating all this; privately, Tweak explains that he trusts in Dredd's integrity, while foreseeing that Spikes (who has eagerly contracted himself Tweak's "agent", owning half of his planet's resources) will not live much longer. This prediction quickly proves correct, as Death Valley holds the greatest peril of all: the remnants of President Booth's robot armies, badly-decayed but still heavily-armed, and programmed to kill any and all Judges. Under the robots' onslaught, the last of the assisting Judges psychologically breaks, and "surrenders" himself to be killed; subsequently, Dredd, Spikes, and Tweak barricade themselves in a nearby Spanish fortress, just barely staving off further attacks. Eventually, the robots' commander voices a parley: as long as Dredd dies, the non-Judges are free to go. Though Dredd is willing to sacrifice himself to ensure the vaccine will reach Mega-City Two, both Tweak and Spikes refuse to abandon him. Soon after, Spikes is dealt a fatal wound, and–encouraged by Tweak's accounts of his planet's riches–uses his last strength on a suicide attack against the robots, proudly dying as "the world's first
