OMG Zombies! price comparison

OMG! Alert! Alert! The City of Redfield has been hit by an outbreak of exploding zombies! For cool and unimportant reasons these suckers literally explode when shot, showering their zombie brethren with gore and causing chain reactions of showering zombie gibs with just a single bullet! As a lone cop armed only with bare wit, a large-calibre sniper rifle and bullets coated in a zombie-exploding pathogen, you are the last man standing at the epicentre of a zombie outbreak. Your mission? To succeed where the police and army failed by clearing the streets of 8 different strains of bloodthirsty zombies and stop Armageddon in its tracks!
