The achievement on steam is called release the kraken iirc, or that's its subtext. So naturally you scope out the sea, and find the boat with bells.thanks. It is working.
So question about Let no joyful voice be heard (Sapienza) achievement. I had to lookup this one because there is no way I would figure it out.
How did you do figure it out? Did I miss some hint on the map like a document or a conversation? Or is it related to some previous Hitman games?
Some secret challenges are much worse, like the golfer thing in bangkok, or tupence in bangkok too
