I’m a big fan of the the Cepheus Journal, the free RPG fanzine for the Cepheus Engine RPG system.
They recently released the 7th issue. It’s a got a theme of espionage.
It’s available for free at https://cepheusjournal.com/downloads/
It has a bunch of interesting articles:
- An article on the various types of spaceship doors
- A new sentient octopoid species
- A discussion of LaGrange points
- Why do people betray secrets? – A discussion of motivations for intelligence source in spy games
- From Visby With Love – A espionage adventure set in 14th century Sweden
I’ve submitted two articles of my own:
- A list of new biological enhancements for the cyberpunk Zaibatsu setting.
- A system for creating and running intelligence networks.
