Dead Rising 2 Tips

Free Zombrex!
Usually you have to search all over or complete an entire mission just to get a single box of Zombrex, but I found there is an exception. Once you gain access to the underground passageways during/after case file 2-2, make your way to the south-eastern corner on the underground map to find a box lying on the floor on one of the inclines. This will get you ahead of Katie's schedule or provide you with enough to give to the man in the mission "Once Bitten".
