I've been searching all over how to stalk for the challenge, and finished the game once but couldn't find anything about it. I did everything I could possibly do and now started a new game+.
There is one action in the JSGA that shows only "??? ??? ???" and is greyed out, even after new game+. I suppose that's what I need to unlock but haven't been able to so far. Is there something specific I need to do to unlock the option to stalk Rose ?
Thank you for your help.
