I just got to thinking that its just kind of super cheap that a pump shotgun in a vent or crawlspace can launch a zombie 50 feet back and with a bunch of people backing the shotguners up with m249s theres really no way to get at them.

if it was just guys with m249s you can get atleast get at them when they reload so why not just ban the use of that particular shotgun in crawlspaces but not the auto since it doesn't knock them back that far and cause that much damage.
