If you're looking for something specific and graphical, you can try my site. I did a "multiple objects" walkthrough, but I was so inexperienced with wordpress at the time, the walkthrough was in chunks. :| for example, if you enter
Allerton complete the rainbow
in the search box, the review comes up first and then the walkthrough comes up. (I've since learned that people can't find stuff in wordpress because the search algorithm is horrid...)
