Have you heard of a gearbox gun? You can get 1 by getting to the mission where you defeat the challenge and get the eridian artifact DO NOT go to trash coast! stay at new haven then go to the house behind Helena pierces that does not have a door knob go in front and the door will open automatically the elevator is super fast so don't jump. down there is a fight between you and 3 psychos. 1 is badass 1 is midget and the other is normal. defeat them all then you will see a treasure box that has a gun and a extra special gun called the Rider it is a fast shotgun but still quite slow. Its maker is Gearbox the company who made the game mostly.
