Just started reading it, it seems very sick. Here's some edit things I've found.
Page 10. "Masive Damage:" instead of massive.
Pages 30+. Footer says Snow Hack where it should say Songbirds
And, finally a weird one. There seems to be remnants of two different combat systems in a couple instances. Volf Knight (p.19) and Berserker (p.15) both reference adding things to attack rolls. On the equipment page (p.32) it shows the modifiers for an attack roll. However, in the actual combat rules (p.96), it implies to only roll a d20 to see if you crit (though it says "just roll damage" suggesting you don't roll a d20 at all). Monsters follow this convention and don't have an attack bonus.
