The Crevice reminds me of a cross between Beyond Red Crater and the Flesh Weavers adventure in Pitford with the Blood sucking zombie creatures that spawn from eggs. I enjoyed the premise and writing. Its a short adventure that can be played in 4-6 hours. There is a lot of area to add on your own whole story and segue to the next one. The ending is abrupt and thats where you need to have your own adventure ready. I liked Mall of Doom the best of all the adventures I've played so far. I'd rate mall of doom 5 stars and crevice 4 stars.
