Cryonics, the science of preserving life through freezing, breaches the chasm between life and death: to exist for a span of time in suspended animation, to be revived in some future world. This allows the <l:2,52>Cryo-Prisons<e> to be built in <l:6,104>cities<e>, where the prisoners are not only kept alive to be released at some later time (probably too late for anyone to care), but also reformed by nanopsychological treatment. An even more sinister aspect of this Advancement are the grim and deadly <l:2,58>Aquatoid<e> units who sabotage undersea colonies.
