[1] Gideon Kibblewhite reviewed From Prussia With Love for Arcane magazine, rating it a 5 out of 10 overall.
[1] Kibblewhite comments that "the book generally pokes fun at its characters, with the story taking the form of a general send-up of the action-adventure format – there's even a tip of the hat made to James Bond.
Those looking for deeper, darker inspiration for Steampunk sessions should look elsewhere.
