[Fred Brackin]

Even though you have armed the PCs with pretty much the least effective v. zombie guns possible they will always do at least 1 pt. Even when halving you don't round down to zero for P-type damage. It still might take 75 shots per zombie.

On the other hand you've armored the PCs to the point that they will take little damage from the zombies. The result might be very long combats.

If there are enough zombies they will probably win when they get close enough to mob-grapple and start peeling off that armor.
