Sure, when you're starting out, commonly found items are useful to ward off low-level enemies before you find more useful weapons, but once Death Claws and other horrendous wasteland monsters get involved, you'll want something more powerful. Though there are plenty of insanely powerful weapons in the post-apocalyptic wasteland of the Commonwealth, there are just as many that are straight up horrible. However, not all of them are all that useful. In the latest installment of the franchise, the world is filled with all kinds of weapons you can find, use, and modify.
The Fallout series has some pretty insane weapons, and Fallout 4 is no different.
