This is a scenario, as the review will tell you, that considers dynamite a common tool of surveyors, and expects a mixed group of people checking a buisiness interest to dig a tunnel with said explosives. That is not even a spoiler: that is the job description that the players get.

The rest of the "review" are spoilers, of course.

The adventure is an idea with a peculiar implementation. As an idea to work with this is nice, and the writing is good. I am not, however sold on either the concept nor the adventure itself. I have no idea what the target of these explosive is supposed to be -the Secrets of Kenya would suggest something, but that is not even alluded to- and I am under the impression that the success hinges on blowing something up with a single skill roll of a 40% skill. Besides all other questions (and there are some): that means that the character fail in 60% of all attempts.

I really think that the writer can do much better: what few descriptions there are read well.

Offering male and female characters (same characters with different names) is certainly nice, but fits in the period like a gatling gun into Cthulhu Invictus. If one really likes pulp action and explosives, this is a fine adventure. Otherwise it needs some remodelling in my opinion.

Recently, I soloed my way through The Romanian Contract (free/pay what you want at DriveThruRPG). It is an open-ended adventure for Call of Cthulhu 7E, but I used the older 5th edition ruleset. . I used the Solo Investigator’s Handbook as the solo engine. In this adventure, the five characters (which are included in the module) are part of a survey team in Romania in the 1920s. The plan is to build an expensive hotel up in the valley. On the very first day, their transportation does not show up and they have to make some decisions. They decide to buy a wagon and a horse to haul their load of dynamite. On day 4 they find The Cave which is filled with monsters. They blow up the cave entrance on day 5. They get to the castle on day 6. During the next few days they set up explosive traps which kill five monsters. On day 9 they hear noises in the secret corridors and Barnett kills one monster with his handgun. On day 10 the butler warns them of the danger that they are in and that the Count’s daughter is imprisoned in the dungeon. That evening they free her. They then leave the country with her (six characters total). When they get back to the company they list all of the reasons why building the hotel is a bad idea. The company goes ahead and builds the hotel. It is successful. It is seized by the communist regime in 1948. – Give this challenging adventure a try!
