Overall, the gun can be considered a much more abundant version of the British Sten. Its high damage and rate of fire makes it the best spray-and-pray gun in the game, as it can clear an entire room with only one magazine. This makes for a very versatile weapon in the campaign, as it only takes two shots to the body to bring down an enemy, although in Call of Duty: United Offensiveit takes up to five rounds.

It does high damage, though this tapers off in Call of Duty: United Offensivealong with high magazine capacity and very little recoil and an adequate rate of fire, except that unlike other machine guns, the MP40 does not have a semi-automatic firing mode. The MP40 is one of the most common weapons in the game, and by default has abundant ammunition. The MP40 Maschinenpistole 40 is a German submachine gun.
