Or, Big *** Guns. I've been looking around the Nexus and what not, and there seems to be a peculiar shortage of new big guns weapons. I mean really, why haven't we seen this http://images2.wikia.nocookie.net/__cb20050719185340/fallout/images/2/23/Big_Guns.gif made into a reality yet?

So basically I'm asking if there's been any obscure mods that add such weapons to the game. God knows they would just be fun to play with if anything.
