Yeah, i remember that part. In Case Zero, it was 12 hours. In Dead Rising 2, three years after Case Zero, the duration was improved from 12 to 24. And as you were saying, because of Nick being immune, it's hard to know if the Zombrex has been improved or not within the years between Dead Rising 2 and Dead Rising 3.
