Yes there are plans for the TWW walkthrough. But as we know, Caleb is a working man and has stuff to do. We don't know when it'll be released. Just calm down and be patient, I expect this thread to be locked anyway :/
It's NOT being worked on at this moment though. I don't think I will be doing this one, but perhaps one of the other staffers will tackle this one. We had one that was being worked on but a staff member, but it got scrapped for various reasons.
