Well it's taken me longer than I imagined it would, but I am finally getting back to this project. I apologize to all of you who've been waiting for more, and will really try to get the rest out on a more reasonable schedule. I hope to have Episode 4 up within a week.
Also, I may be renaming this tutorial series and reposting it...mostly because I have ended up changing quite a few things in the adapation. So I may call it something else and just give Zombie Nirvana credit for being the source and inspiration for the tutorials. Keep an eye out, I also plan on doing some other tutorial stuff in the future.
Thanks to all of you who commented and have used the tutorial!
