Played for a few hours last night, mostly getting my daily/weekly stuff out of the way, did a bit of the new stuff too, seems quite fun so far.
**TIP** dont use explosive weapons when you need to find something, I spend AAAAAAges trying to find one of the corpses personal belongings before I realised I had blown it off the edge of a hill.
Got to rank 15 last night. Nice and easy so far. Did re-roll the alcohol challenges though. Did a bit of the new area too. Seems to be a couple of bugs getting a quest to continue. Killing all the lost in the manor before getting into the new vault. Took 4 attempts in a public world and nothing, jumped to a private one and it worked first time.
If you mean the hat at the bottom of the cliff, that's where it spawns. Bloody silly place.
