I can already see the place going down with our heroes escaping, the idiots have the usual stupid cliche of a zombie chained in to "teach it a lesson", so stupid.

The fact they keep a zombie so close means the parasite needs a bite to transfer, honestly this makes me think that countries like America are safe as they had enough guns to fend them off.
