At the end of the Ice Age, The Machine came from outer space with the purpose to change men into mutants. 2707, during a battle between corporations, the great seal is broken and The Machine works again transforming soldiers and civilians into hordes of mutants. The corporation unite against the new threat, but the forces are not equal. The lucky ones manage to evacuate to colonial worlds. The rest are doomed. Only a small group of the bravest soldiers under the command of Maj. Mitch Hunter is set deep into the dungeons to install an ancient mechanism that will destroy The Machine. This is the only hope of humanity for survival.
