Blow-em' brew

Blow-em' brew is a perk whose effect is to inflate any zombie shot with it more than once, which slows down that zombie and blocks the zombies behind him. This is an advantage when buying yourself time to pack-a-punch or get a weapon from the mystery box or buying a perk if you shoot the first zombie in a train in front of a door, which causes the zombies behind him to stop in their tracks. It's effects are best matched with double tap since it makes one shot become two, but it can be a nuisance if you accidentally block yourself while trying to shoot a zombie out of a doorway, which can prove fatal if being chased and in high rounds. It's cost is 2000.

Male characters might occasionally say "thanks bro" after drinking this perk, and female ones might say "Eww, no" for, obvious reasons.
