"A 40mm shotgun round consisting of 12 tungsten darts. Its effects are devastating at short range. Although it is considered a multi purpose round , it is most effective in close quarters during urban operations."
— In-game description
The 40mm Shotgun is a weapon attachment found in Battlefield: Bad Company 2. It is simply a canister round that is fired from a 40mm grenade launcher. It is unlocked after getting 11000 points with the Assault class. It is loaded and fired exactly like a grenade, except that no compensation must be made for a ballistic trajectory. It inflicts very high damage against infantry, has a slow reload time, and a relatively short effective range. Achieving kills at medium range is possible, but improbable. The 40mm Shotgun deals the most damage of all shotguns and has no damage drop off.
