Just found this with sidey ontop of the bridge where you find the suprise MF blueprint, in a lock box, not sure if it is there for everyone but it dose over 1k damage and one hits everyting you hit with it. So far I can't find any other information about this on reddit or youtube so it looks like we found it first >.<
Sweet lord, I went up there, no weapon unfortunately. Something that may help DS when you post an item you found, try posting the time you found it in the game. I am not sure if that's how it generates, but it's a possibility.
I got up there and inside the box was a Police Baton lol Random weapons in most boxes i think, was a good climb up there though lmao
