Designed specifically for riot control situations. Its primary fire is similar to your average run-of-the-mill pump action shotgun, but with a much larger bore to widen the weapon's spread. While this severely hinders accuracy, its wider area of effect and increased number of pellets makes it much easier to hit several targets at once in small groups.
Its secondary fire switches from standard buckshot rounds to heavier, slower shot that ricochets off of walls, at the cost of overall damage and much, much slower travel speed.
