About The Medusa Report, from BoardGameGeek:
After four long decades serving a secret intelligence agency, an embittered Abigail Vandermist suddenly drops off the map. She has found something out. Something to do with an old rescue mission into the heart of the USSR, a nuclear physicist, and her own enigmatic father.
With Abby on the run, you're back to square one, and you are not the only ones trying to get to her first...
The Medusa Report is a co-operative tabletop puzzle game. A treasure trove of touch-real confidential items from a Cold War infiltration mission. Investigate the mysterious organization S.E.A., discover what really happened near Nikitagrad in 1974, and above all: find out where Abigail is hiding!
This is a sequel to The Vandermist Dossier, which title being standalone, yet forming a longer story together. The game works the same as part 1. You first receive a letter from Helena by mail, asking you for your help. A few days later a package arrives by mail with a report made by Abigail, Helena's sister. You have to deciper the clues to find the current location of Abigail. When you succeeded in doing so, you can upload it to Helena on a website to find out if you have the correct solution.
