Damn, harsh words from the pringles guy.
Finally for the L4D mapping tutorials, I want to see what the community can make.
Pringles guy? It's the monopoly man!
I say no you won't because based on his avatar and the fact that this guide is for really new mappers, it probably won't help him much. Sure, you'll learn how to make a box with a light and nav mesh, and maybe even a ladder, but you're not going to be a pro after reading it.
Also i'm confused as to how this was found, there's no link on their forums or on the site, how did it surface?
