The Benelli M4 Super 90 is a semi-automatic shotgun which appears commonly within the Diseased Productions games' arsenal. It is often categorized as a higher tier weapon, capable of taking down most enemies with one shot.
As a shotgun, the Benelli M4 fires in a spread pattern, encouraging usage in mid to close range combat. While it requires the player to consistantly click to shoot, it has a fast rate of fire; oftenly being able to be refired after the recoil settles. With the longer length of the gun, it can reach and hit targets through some floors and walls.
Visually, the gun usually sports a collapsible stock.
