Written by Paul Baldowski, creator of The Cthulhu Hack and contributor to several sourcebooks for the Paranoia RPG, Valkyrie Nine is a short investigation for The Cthulhu Hack system with additional rules for handling its futuristic setting and player character generation.
The investigators are all AI-controlled repair drones (think astromech droids from Star Wars or service robots from Silent Running) that are activated in medias res during a major system failure at a lunar mining base. But not everything is as it seems. Without giving away the plot, the players must work within a time limit in order to deal with the situation and save the surviving crew from the literal unseen forces against them.
The author helpfully provides copious playtest notes and GM guidance such as using sounds when running the scenario. Appropriate counters or miniatures could also be placed on the overview maps to represent where everyone is in the sandbox environment of the Valkyrie station.
One thing I would have liked is a copy of the drone unit character generation rules from the background section included in the handouts. The five pregenerated characters still allow a large amount of customization on the part of the players.
While it could use another round of editing, both the unique setup and "Tomato in the Mirror" surprise conclusion will make this scenario a memorable investigative experience for both the GM and players.
