44. Carnage Shotguns
Of Borderlands' purported 17,000,000-plus possible firearms, we can't think of any that gave us more joy the first time we picked one up than a Carnage-class shotgun. They come in many, many flavors, but one thing they all had in common was that they actually shot rockets. There's no way Gearbox was ignorant of how awesome this is when they designed it; the in-game description even reads, "Holy crap! It Shoots rockets!"
