Sorry for question... But who is Zem? They say he is Zombie Emperor... But i don't see zombies(?). Maybe i understood something wrong? I thought zombie is a dead man( Residence of Evil, Walking Dead, at last STALKER series, there is zombie are corpses, or infected peoples, or hypnotises at mutants)... But Zem is just puppet!(?) He and his zombies are... not frightening at all and they are not dead or hypnotises people... Please, explain me somebody!
