A well rounded companion for those desiring to run a horror game. Most of the major bases are covered and elements from books and film are present (there's even a puzzle box resembling the Lament Configuration from the Hellraiser movies). The only thing I'd like to have seen are additional rules covering zombie apocalypse type settings. I'm not sure if this was omitted because of a perceived redundancy with the Zombie Run book but it's a sub genre that would have given the companion a more complete feel.
As it stands this is a great book and a valuable addition to the Savage Worlds line.
