ABOUT SURPRISE THREAT!:
Surprise Threat! is a collection of resources, house rules, and musings about the tabletop role-playing game, Shadowrun: Anarchy from long-time gamer, Kevin Duncan (aka. Gingivitis on many forums).
These are free and fan-made. I created these to help with my own Shadowrun: Anarchy campaigns, which I have been running since 2016. I shared them because they worked for me and hopefully, they can inspire you in your own games.
