Hey pstar,
I still have the project files but I don't think I'll rehost the files. I removed them to save some space on Dropbox 6+ months ago and have not worked on the project for over a year. I don't know how friendly it would transition to unity 5 and newer playmaker versions, so once I would tackle that and get it compiling I would have to strip the ai chunks out from the project. More work than id like =/
iirc the videos show the concepts and ideas I used, maybe you can derive enough from there to roll your own?
