For ex:
A sawed off shot gun is pretty awesome however. What if some one combined a radar gun with a shotgun via duct tape and added a Portal mod. The portal would open in front of the gun when fired, and the radar would detect how far the target is with the radar gun or whatever portable radar they were able to salvage. and open a portal right in front of the target. Allowing a shotgun to fire point blank at long range. I guess you can call it a worm whole generator.
Of course the whole portal thingy would have to be stolen from aliens or enclave or something. I got this idea from playing portal and reading the Johnny Mnemonic short story. Or the portal with Radar combo can be modifier and used with any gun.
Another thing i loved from the first game was the Gauss rifle. I didn't like something about it though. If you read about Gauss Rifles http://fallout.wikia.com/wiki/Gauss_rifle & http://en.wikipedia.org/wiki/Coilgun then you'll see that they need a projectile to work. So really the Gauss Rifle you get in Fallout 3 Operation: Anchorage should of used up a Microfusion Cells and some other form of Ammunition. I think this really should be a mod that increases range and damage but as a drawback it needs energy to charge it.
