 is a gun that fires a cone spread of bullets and has strong knockback.

Trivia

 * So called elephant guns were very large weapons used for hunting big game during safaris, mostly in Africa. They had tremendously large bores of up to 25mm and were fired at close range, ensuring they would knock out the huge animals they were intended to stop. While the gun present in the game fires a spread, elephant guns loaded single lead projectiles, but they could be rifled or smoothbore.
 * Piano keys used to be made from elephant tusk ivory, hence "pianos out of teeth".
 * "An inelegant weapon for a less civilized age" Is a reference to Star Wars, where the reverse of the phrase is used to describe a lightsaber.
 * The reload animation could be a reference to the Super Shotgun from the Doom games.
