My favorite weapon was a legendary rifle that had a shotgun mode, a lot of the guns have different modesc many shotguns, and its really easy to get legendaries (way too easy, while it was too hard in past games) I had a full inventory of legendaries constantly from mid way to endgame, kinda hated that because I liked ll my options. Liked the flamethrower rifle that when reloaded became a turret that ran around, abused those lol (got that legendary a few times in different forms)

I haven't played 3, but loved 2. Still haven't finished it, maybe should.

There's a bunch of generic weapons (themed by manufacturer and weapon type), but there's also some unique ones. Bane in particular was a really funny one to discover.
