Per's personal website which has his walkthrough has disappeared for some while, and so does him. His last activity in NMA is almost 6 years ago. I guess he just lost interests in Fallout and maybe will never come back or show up? But obviously, there are still quite some people who would like to play FO1 and FO2 and still need a nearly-ultimate walkthrough (me, for example), as Per said everybody could distribute walkthrough, I think it will not be a bad idea if we put his walkthrough in downloads? I have saved both walkthrough in .pdf and can share to person who wants it, by the way.
