I really enjoyed this. From the very OSR feel, to the open way that much of the content can be applied to a similar themed adventure, particularly the unique mechanics and various roll tables offered throughout, this was a great choice.
The various undead NPCs are fun and I'm looking forward to my players encountering them, the accompanying artwork for each going a long way to add some nice feel and depth.
I won't spoil the many locations presented for the hex crawl, but they're nicely varied considering how the theme could so easily have been constricted by the choices.
For the price I would definitely recommend this, it's a great tool to have in your arsenel and I suspect I'll be keeping it nearby for whenever a campaign starts to get a little spooky!
