theirs a weapons mod blueprint that you get in game (i think as a quest reward), its called the Heavy Mod. in the game, their is a weapon called the Heavy Hammer. i found this out on accident and lol'ed for a couple seconds, but if you use the Heavy Mod blueprint on the Heavy Hammer, it becomes the Heavy Heavy Hammer. (it also reminded me of those Glad trashbag lines: "Hefty Hefty Hefty")
I HAVE MY PS4 BACK. WE HAVE A GREEN LIGHT FOR OPERATION GAMING.
I REPEAT, WE HAVE A GREEN LIGHT FOR OPERATION GAMING.
