I've completed every thing in the game, I am level 50 and 50 street cred as well. The only thing I have to do is the nocturne mission, yet I for some reason haven't gotten the Watson achievement on steam. I have 38 out of 44 achievements. I have 2 of the 4 endings left to do but I'm not sure if there's somehow something I've missed or if this is bugged?
