First of all, for only $2 its very hard to go wrong with this book. I was especially pleased to see something that would ordinarily have been a prestige class being expanded into a full 20 level class. For those of you considering this, let me try to give you a better idea of what you're getting:
The Beast Lord = Tarzan
The Hunter = super sniper
The Outdoorsman = survivalist
The Partisian = specialized against multiple opponents
The Trapper = "bring 'em back alive"
Table formatting would really be the only thing that I could say could use some work but this is easily worth the money you'll pay for it.
