I did it at level 30, Now I heeded what the tip said and just ran through, and don't get me wrong...there was alot of them...but problem was they were all zombies..and I don't think I got hit once, got to the end and just felt like I could have just strolled through :)
Just did the second chapter, found it pretty good, but I've gotta ask, the Winds of Magic, Warhammer easter egg? Anyway I can't wait to see the next chapter, quite compelling ( undead in final part could use more of an intimidation factor only real critic without anything spoilery )
