Is cloning the future a pre-crime?

Dr A. Noid, perpetrator of the Great Biological Holocaust, remains on the loose in a post-apocalyptic world crawling with slime-oozing zombies high on 'SLU'. Naturally, as a totally coincidental Mad Max look-a-like bounty hunter, we're obliged to engage our ATV in obliterating all vehicular threats in our path whilst dodging mines and gun turrets. Because battering ram combat vehicles generally won't fit through pedestrian doorways, we must occasionally exit to explore buildings on foot with a view to euthanising anything that shambles or groans suspiciously.
