The "Preacher" is a double-barreled shotgun, found in Zombie Army Trilogy.
The Preacher is a hammerless coach gun, but does not seem to be based on any real model in particular.
It deals massive damage, and has decent range. and a fast rate of fire, but it is offset by having a total capacity of two shots.
- Oddly, the Preacher doesn't function as a break action/breech loader, and is reloaded as though it had a tubular magazine, which is odd as spent shells are never shown to be ejected from it.
