Fallout 4 unique weapons

There are several unique weapons in Fallout 4, weapons of which only one exists in the game world. Some are found in specific locations while others are obtained as quest rewards.

These are different from legendary weapons which are randomly generated from a table of possible effects. Some unique weapons also have legendary effects without the normal legendary weapn prefix (eg. assassin's, hunter's, ghoul slayer's).
