Reception.
The reviewer from the online second volume of "Pyramid" stated that "In comparison with the classic period of the 1920s, the modern day has seen relatively scant coverage from Chaosium for their venerable RPG, "Call of Cthulhu". This is not to belittle their releases for the modern day such as "Utatti Asfet", "The Stars Are Right", or "The Resection of Time", but many feel that none have come close to Pagan Publishing's "Delta Green" setting and books in terms of tone and feel. Yet now Chaosium have published a contemporary set campaign that can justifiably said to come very close."
"Unseen Masters" won the Origins Award for "Best Role-Playing Game Adventure" of 2001.
